media: dvb_frontend: fix wrong cast in compat_ioctl

2018-04-04T10:27:28+00:00

FE_GET_PROPERTY has always failed as following situations: - Use compatible ioctl - The array of 'struct dtv_property' has 2 or more items This patch fixes wrong cast to a pointer 'struct dtv_property' from a pointer of 2nd or after item of 'struct compat_dtv_property' array.

media: dvbdev: handle ENOMEM error at dvb_module_probe()

2018-03-22T13:01:33+00:00

If allocation of struct board_info fails, return NULL from dvb_module_probe(). Fix this warning: drivers/media/dvb-core/dvbdev.c:958 dvb_module_probe() error: potential null dereference 'board_info'. (kzalloc returns null) Signed-off-by: Mauro Carvalho Chehab

media: dvbdev: fix building on ia64

2018-03-07T09:11:50+00:00

Not sure why, but, on ia64, with Linaro's gcc 7.3 compiler, using #ifdef (CONFIG_I2C) is not OK. So, replace it by IS_ENABLED(CONFIG_I2C), in order to fix the builds there. Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab

media: dvb_ca_en50221: fix severity of successful CAM init log message

2018-03-06T15:46:41+00:00

A successful CA module initialisation isn't an error. Change the log print to info severity accordingly. Cc: Jasmin Jessich Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: dvb-core: add helper functions for I2C binding

2018-03-06T10:00:31+00:00

The dvb_attach()/dvb_detach() methods are ugly hacks designed to keep using the I2C low-level API. The proper way is to do I2C bus bindings instead. Several modules were already converted to use it. Yet, it is painful to use it, as lots of code need to be duplicated. Make it easier by providing two new helper functions: - dvb_module_probe() - dvb_module_release() Signed-off-by: Mauro Carvalho Chehab

media: dvb: update buffer mmaped flags and frame counter

2018-02-23T16:44:08+00:00

Now that we have support for a buffer counter and for error flags, update them at DMX_DQBUF. Signed-off-by: Mauro Carvalho Chehab

media: dmxdev: Fix the logic that enables DMA mmap support

2018-02-23T10:27:10+00:00

Some conditions required for DVB mmap support to work are reversed. Also, the logic is not too clear. So, improve the logic, making it easier to be handled. PS.: I'm pretty sure that I fixed it while testing, but, somehow, the change got lost. Signed-off-by: Mauro Carvalho Chehab

media: dmxdev: fix error code for invalid ioctls

2018-02-23T10:23:04+00:00

Returning -EINVAL when an ioctl is not implemented is a very bad idea, as it is hard to distinguish from other error contitions that an ioctl could lead. Replace it by its right error code: -ENOTTY. Signed-off-by: Mauro Carvalho Chehab

media: dvb: fix DVB_MMAP symbol name

2018-02-23T10:20:01+00:00

CONFIG_DVB_MMAP was misspelled either as CONFIG_DVB_MMSP or DVB_MMAP, so it had no effect at all. This fixes that, to make it possible to build it again. Fixes: 4021053ed52d ("media: dvb-core: make DVB mmap API optional") Signed-off-by: Arnd Bergmann Signed-off-by: Mauro Carvalho Chehab
