From: Peter Hurley Date: Fri, 29 Nov 2013 23:00:35 +0000 (-0500) Subject: drivers/misc/ti-st: Prefer tty_driver_flush_buffer X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=94459a975b7d4d70c20df1a32d63825469b8d4cc;p=linux-beck.git drivers/misc/ti-st: Prefer tty_driver_flush_buffer The tty core provides an interface for flushing the driver's write buffer: tty_driver_flush_buffer(); prefer the provided interface over open-coded. Open-coding can lead to errors such as the duplicated call in the st_kim driver.
