Subject: [PATCH 1/9] fbdev: shmobile: fix snprintf truncation

From: Arnd Bergmann <arnd@...db.de>

The name of the overlay does not fit into the fixed-length field:

drivers/video/fbdev/sh_mobile_lcdcfb.c:1577:2: error: 'snprintf' will always be truncated; specified size is 16, but format string expands to at least 25

Make it short enough by changing the string.

Fixes: c5deac3c9b22 ("fbdev: sh_mobile_lcdc: Implement overlays support")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
