Subject: [PATCH] staging: fbtft: fix build error

while building on i386 it gives a build warning about msg undeclared.

Fixes: e6ffd1ba55a4931c ("staging: fbtft: fix out of bound access")
Reported-by: kbuild test robot <fengguang.wu@...el.com>
Signed-off-by: Sudip Mukherjee <sudip@...torindia.org>

It was my mistake that I missed removing msg in the original patch.
But I am still surprised that the build error does not appear when I am
doing allmodconfig on x86_64 and x86. It only shows on ARCH=i386.
This has been tested with make ARCH=i386 allmodconfig
