* [PATCH 1/3] tty: serial: msm: Move header file into driver @ 2016-05-12 1:02 ` Stephen Boyd 0 siblings, 0 replies; 14+ messages in thread From: Stephen Boyd @ 2016-05-12 1:02 UTC (permalink / raw) To: linux-arm-kernel This header file is only used by the driver, so let's merge the two together to reduce files and make it easier to see the whole driver without flipping through two files. This also makes it easier to use the structures defined in msm_serial.c in the functions that are defined in msm_serial.h by placing them in the proper locations.

Drop those ones. The irq.h header really should be interrupt.h because this is an interrupt user and not an interrupt chip. Finally add wait.h for the wake_up*() usage in this driver and kernel.h for container_of().
