media: staging: cxd2099: Fixed buffer mode

2017-06-26T11:17:49Z

The buffer mode was already implemented in this driver, but it did not work as expected. This has been fixed now, but it is still deactivated and can be activated by removing a comment at the begin of the file. Original code change by Ralph Metzler, modified by Jasmin Jessich and Daniel Scheller to match Kernel code style.

media: ngene: Replace semaphore i2c_switch_mutex with mutex

2017-06-24T19:42:34Z

The semaphore 'i2c_switch_mutex' is used as a simple mutex, so it should be written as one. Semaphores are going away in the future. Signed-off-by: Binoy Jayan Signed-off-by: Mauro Carvalho Chehab

media: ngene: Replace semaphore stream_mutex with mutex

2017-06-24T19:42:00Z

The semaphore 'stream_mutex' is used as a simple mutex, so it should be written as one. Also moving the mutex_[lock/unlock] to the caller as it is anyway locked at the beginning of the callee thus avoiding repetition. Signed-off-by: Binoy Jayan Signed-off-by: Mauro Carvalho Chehab

media: ngene: Replace semaphore cmd_mutex with mutex

2017-06-24T19:36:40Z

The semaphore 'cmd_mutex' is used as a simple mutex, so it should be written as one. Also, replace down with mutex_destroy to ensure sane state when ngene_stop is called. Signed-off-by: Binoy Jayan Signed-off-by: Mauro Carvalho Chehab

media: ddbridge: use dev_* macros in favor of printk

2017-06-24T12:41:55Z

Side effect: KERN_DEBUG messages aren't written to the kernel log anymore. This also improves the tda18212_ping reporting a bit so users know that if pinging wasn't successful, bad things will happen. Since in module_init_ddbridge() there's no dev yet, pr_info is used instead. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: ddbridge: make (ddb)readl in while-loops fail-safe

2017-06-24T12:41:30Z

Reported by smatch: drivers/media/pci/ddbridge/ddbridge-core.c:1246 input_tasklet() warn: this loop depends on readl() succeeding drivers/media/pci/ddbridge/ddbridge-core.c:1768 flashio() warn: this loop depends on readl() succeeding drivers/media/pci/ddbridge/ddbridge-core.c:1788 flashio() warn: this loop depends on readl() succeeding Fix this by introducing safe_ddbreadl() which will wrap ddbreadl and checks for all bits set in the return which indicates failure, and return 0 in that case. Usable as drop-in-replacement in all affected while loops w/o having to change the logic. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab
