* [media] ttusb_dec: avoid the risk of go past bufferMauro Carvalho Chehab2016-09-22
| | | | | | | | | | | | | | | | Fixes this smatch warning: drivers/media/usb/ttusb-dec/ttusb_dec.c:243 ttusb_dec_handle_irq() error: buffer overflow 'rc_keys' 26 <= 126 As the RC keys should be enabled previously, via: set_bit(rc_keys[i], input_dev->keybit); It wouldn't go past the buffer in practice. Yet, as bad things may happen when going past buffer, it doesn't hurt adding a check here. While here, fix CodingStyle issues on the routine.

* [media] ttusb-dec: constify ttusbdecfe_config structureJulia Lawall2015-11-19
| | | | | | | | | | | | The ttusbdecfe_config structure is never modified, so declare it as const. Other references to this structure type were already declared as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] dvb: get rid of enum dmx_successMauro Carvalho Chehab2015-10-06
| | | | | | | | | This enum is not actually used anymore. The only value used from the enum is DMX_OK, passed as a parameter on two callbacks. Yet, this value is not used anywhere. So, just remove it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab2015-06-09
| | | | | | | | | | | | | | | | | The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

* [media] dvb-usb: fix error handling in ttusb_dec_probe()Alexey Khoroshilov2013-10-03
| | | | | | | | | | | | | | | | | | | | There is an asymmetry in ttusb_dec_init_usb()-ttusb_init_rc() and ttusb_dec_exit_usb()-ttusb_dec_exit_rc() in terms of resources allocated-deallocated. irq_urb and irq_buffer are allocated in ttusb_dec_init_usb(), while they are deallocated in ttusb_dec_exit_rc(). As a result there is a leak of them in ttusb_dec_probe(). The patch fixes the asymmetry and a leak on a failure path in ttusb_dec_init_usb(). By the way, it - removes usage of -1 as a custom error code, - replaces GFP_ATOMIC by GFP_KERNEL in usb_alloc_coherent() in ttusb_dec_init_usb() as soon as all other memory allocation done with GFP_KERNEL; - refactors ttusb_dec_boot_dsp() in an equivalent way except for returning 0 instead of 1 if ttusb_dec_boot_dsp() succeed in (!mode) branch.

* [media] demux.h: Remove duplicated enumMauro Carvalho Chehab2013-04-08
| | | | | | | | | | | | "enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
