Subject: vt: drop redundant might_sleep() in do_con_write()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c57c1644c266a42579dccd919c11d247be48cca5;p=linux.git

vt: drop redundant might_sleep() in do_con_write()

The might_sleep() in do_con_write() is redundant because console_lock()
already contains might_sleep().  Remove it.
