Subject: [PATCH] compat: remove compat_printk
Date: Fri, 17 Jun 2016 16:26:21 +0200	[thread overview]
Message-ID: <20160617142903.3070388-1-arnd@arndb.de> (raw)

After 7e8e385aaf6e ("x86/compat: Remove sys32_vm86_warning"), this
function has become unused, so we can remove it as well.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
