| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some functions definitions have either the initial open brace and/or the closing brace outside of column 1. Move those braces to column 1. This allows various function analyzers like gnu complexity to work properly for these modified functions.

| * | media: v4l2-ioctl: rename a temp var that stores _IOC_SIZE(cmd)Mauro Carvalho Chehab2018-03-261-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of just calling it as "size", let's name it as "ioc_size", as it reflects better its contents. As this is constant along the function, also mark it as const. Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Smatch produces two warnings when building this file: ./arch/x86/include/asm/bitops.h:433:22: warning: asm output is not an lvalue ./arch/x86/include/asm/bitops.h:433:22: warning: asm output is not an lvalue On some asm instructions. I suspect that those asm instructions might not be producing the right code, so, better to use two intermediate vars, get rid of the warnings and of the risk of producing a wrong code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the logic there is correct, it tricks both humans and machines, a the check if "i" var is not zero is actually to validate if the "frames" var was initialized when the loop ran for the first time.

| * | media: cec: improve CEC pin event handlingHans Verkuil2018-03-224-18/+39

It's about 160 ms worth of events and if the Raspberry Pi is busy, then it might take too long for the application to be scheduled so that it can drain the pending events. Increase these buffers to 800 events which is at least 2 seconds worth of events. There is also a FIFO in between the interrupt and the cec-pin thread. The thread passes the events on to the CEC core. It is important that should this FIFO fill up the cec core will be informed that events have been lost so this can be communicated to the user by setting CEC_EVENT_FL_DROPPED_EVENTS. It is very hard to debug CEC problems if events were lost without informing the user of that fact. If events were dropped due to the FIFO filling up, then the debugfs status file will let you know how many events were dropped.
