Sergey Shtylyov e8e4a470b6 fbdev: core: syscopyarea: fix sloppy typing
In sys_copyarea(), the local variable bits_per_line is needlessly typed as
*unsigned long* -- which is a 32-bit type on the 32-bit arches and a 64-bit
type on the 64-bit arches; that variable's value is derived from the __u32
typed fb_fix_screeninfo::line_length field (multiplied by 8u) and a 32-bit
*unsigned int* type should still be enough to store the # of bits per line.

analysis tool.
