Subject: [PATCH 3.16.y-ckt 048/110] ARM: gemini: fix compiler warning due wrong data type

3.16.7-ckt13 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans Ulli Kroll <ulli.kroll@...glemail.com>

commit 31fc835fc787aad38e8985d593f8ad0d18825323 upstream.

This patch fixes a compiler warning in gemini_restart()
issued by commit 7b6d864b48d9 ("reboot:arm: reboot_mode
changes from char to enum reboot_mode").

arch/arm/mach-gemini/board-rut1xx.c:93:2: warning: initialization from incompatible pointer type

The warning is harmless, and the patch does not need to
be backported to stable kernels.

Fixes: 7b6d864b48d ("reboot:arm: reboot_mode changes from char to enum reboot_mode.")
