| Subject: fbdev: shmobile: fix snprintf truncation |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| [ Upstream commit 26c8cfb9d1e4b252336d23dd5127a8cbed414a32 ] |
| |
| 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. |
