From: Jiri Slaby Date: Wed, 20 Apr 2011 08:43:17 +0000 (+0200) Subject: TTY: serial_core, remove superfluous set_task_state X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c831cff256c86588976e66bef7897633d534846c;p=linux-beck.git TTY: serial_core, remove superfluous set_task_state msleep* is guaranteed to return with TASK_RUNNING task state. And since there is no other set_task_state in the paths of uart_wait_until_sent, we need not to set_task_state to TASK_RUNNING.
