Subject: [PATCH] video: fbdev: sis: sis_main.c: Cleaning up wrong type in format string

Wrong type in printf format string, requires 'unsigned int'
but the argument type is 'int'

This was found using a static code analysis program called cppcheck

Perhaps it'd be better to change the type of mydepth
to __u16 as that's the type of lfb_depth
