Subject: [PATCH] tty_buffer: Fix distinct type warning
Date: Tue, 9 Mar 2010 18:54:28 +0800 [thread overview]
Message-ID: <1268132068-5459-1-git-send-email-antonf@turbolinux.com.cn> (raw)
CC drivers/char/tty_buffer.o
drivers/char/tty_buffer.c: In function ‘tty_insert_flip_string_fixed_flag’:
drivers/char/tty_buffer.c:251: warning: comparison of distinct pointer types lacks a cast
drivers/char/tty_buffer.c: In function ‘tty_insert_flip_string_flags’:
drivers/char/tty_buffer.c:288: warning: comparison of distinct pointer types lacks a cast
Fix it by replacing min() with min_t() in tty_insert_flip_string_flags and
tty_insert_flip_string_fixed_flag().
