* | V4L/DVB (5955): Add support for DiB7070-based devicesPatrick Boettcher2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This changeset adds support for DiB7070P-based devices by adding the dib0070-driver and putting the appropriate layouts into dib0700_devices.c It also includes a new firmware for the dib0700 which is necessary to make the DiB7070-boards work and it also should fix the i2c-problems on some boards.

* | V4L/DVB (5954): Sync with DiBcom Driver Release 2.1.3 + some improvementsPatrick Boettcher2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changesets syncs the OpenSource driver for DiBcom demodulators with version 2.1.3 of DiBcom reference driver. There were some improvements since the last release for linux-dvb, e.g.: - stepped AGC startup - less space for initialization - diversity synchronization Furthermore this changeset contains the following things: - latest AGC settings for MT2266-based devices (namely Nova-TD and other) will improve the sensitivity - support for STK7700D reference design in dib0700-devices - remove some line-breaks when debugging is enabled - getting rid of layer between frontend_parameters and ofdm_channel used in dib*-drivers Signed-off-by: Patrick Boettcher <pboettcher@dibcom.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| | | | | | | | | | | | | | | | | | | | | | This patch adds support for the Samsung S5H1409 demodulator, also known as the Conexant CX24227 demodulator. 8VSB mode has been tested and QAM has been implemented based on the spec, although it's untested.

* | V4L/DVB (5947): Adding support for the MT2131 tuner.Steven Toth2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Microtune MT2131 tuner. 8VSB mode has been tested but QAM support will likely require more register work. Hauppauge have not announced any QAM devices using the MT2131 so QAM remains undone. For legal reasons, Microtune allowed us to write a GPL driver providing we did not document in significant detail any of the registers. This explains the lack of comments or defined on register names. Signed-off-by: Steven Toth <stoth@hauppauge.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| * V4L/DVB (6042): b2c2-flexcop: fix Airstar HD5000 tuning regressionTrent Piepho2007-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Git changeset 6bdcc6e6dbab8daffd05e5026486f34ba41a6c72 dropped the stand-alone lgh06xf module, whose functionality was absorbed into the dvb-pll module. However, there was a minor difference between the code in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop devices using the LG-H06xF NIM. dvb-pll will probe for the presence of an i2c pll chip by performing a single byte read, the lgh06xf driver did not do this. Unfortunately, the code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads as a probe. Such probes with the current code will always fail. In order to work around this problem, and restore proper functionality of the Airstar HD5000 device, this hack was created to make the probe appear to succeed. The single byte read in dvb_pll_attach is the only place where such a probe would ever occur, so this change is safe, and will not affect any other devices. Of course, if one knew how to actually perform the read operation, it would be better to go that route. In the meantime, however, we must apply this workaround, in order to prevent the regression that causes tuning to fail on the Airstar HD5000 ATSC device. Thanks to Jarod Wilson, who had originally reported this regression, and to Geoffrey Hausheer, whose original workaround patch led us to find the actual cause of the problem.

* | USB: fix DoS in pwc USB video driverOliver Neukum2007-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | the pwc driver has a disconnect method that waits for user space to close the device. This opens up an opportunity for a DoS attack, blocking the USB subsystem and making khubd's task busy wait in kernel space. This patch shifts freeing resources to close if an opened device is disconnected.

* | USB: Fix a memory leak in em28xx_usb_probe()Jesper Juhl2007-08-22
|/ | | | | | | | | | | | | | | | | If, in em28xx_usb_probe() the memory allocation dev->alt_max_pkt_size = kmalloc(32* dev->num_alt,GFP_KERNEL); fails, then we'll bail out and return -ENOMEM. The problem is that in that case we don't free the storage allocated to 'dev', thus causing a memory leak. This patch fixes the leak by freeing 'dev' before we return -ENOMEM. This fixes Coverity bug #647. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
