* sd: Fix rw_max for devices that report an optimal xfer sizeMartin K. Petersen2016-06-01
| | | | | | | | | | | | | | | For historic reasons, io_opt is in bytes and max_sectors in block layer sectors. This interface inconsistency is error prone and should be fixed. But for 4.4--4.7 let's make the unit difference explicit via a wrapper function.

* scsi_lib: correctly retry failed zero length REQ_TYPE_FS commandsJames Bottomley2016-05-22
| | | | | | | | | | | | | | | | | | | When SCSI was written, all commands coming from the filesystem (REQ_TYPE_FS commands) had data. This meant that our signal for needing to complete the command was the number of bytes completed being equal to the number of bytes in the request. Unfortunately, with the advent of flush barriers, we can now get zero length REQ_TYPE_FS commands, which confuse this logic because they satisfy the condition every time. This means they never get retried even for retryable conditions, like UNIT ATTENTION because we complete them early assuming they're done. Fix this by special casing the early completion condition to recognise zero length commands with errors and let them drop through to the retry code.

| * | | | [media] tvp5150: return I2C write operation failure to callersJavier Martinez Canillas2016-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tvp5150_write() function calls i2c_smbus_write_byte_data() that can fail but does not propagate the error to the caller. Instead it just prints a debug, so callers can't know if the operation failed. So change the function to return the error code to the caller so it knows that the write failed and also print an error instead of just printing a debug information. While being there remove the inline keyword from tvp5150_write() to make it consistent with tvp5150_read() and also because it's called in a lot of places, so making inline is in fact counter productive since it makes the kernel image size to be much bigger (~16 KiB).

The demodulator needs firmware, available for example here: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/ The demodulators sit on the same I2C bus and their addresses are 0x64 and 0x67. The tuners are behind the demodulators and their addresses are 0x60 and 0x63. Signed-off-by: Olli Salonen <olli.salonen@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

A previous commit removed this Kconfig option, as it is apparently harmful, but did not update the driver code which relied on it. This patch reworks the firmware loading into the start_feed callback. At this point we can be sure the rootfs is present, thereby removing the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.
