This is a static checker fix and not something I can test. The intent
of the code here is to set some bit flags. For a logical OR the ">> 1"
shift wouldn't make a difference. So it should be using a bitwise OR.

The piece of code that checks for LCDA in xgifb_probe() just checks for some

that should be executed are commented).
As nothing is really being done, the code can be safely removed.

For TV Devices:
The values taken from XGI_TVDelayList are always overwritten with the
values from XGI_TVDelayList2 since the if condition for using the values
from XGI_TVDelayList2 is identical with the check to enter this scope and
thus always true.
The delay values in XGI_TVDelayList2 is always 0x22 so we
can simply replace it with this constant value.
For LCD Devices:
The LCD_DelayCompensation field is always set to 0x12 so we can simply
replace this field with a constant value.
This saves about 500 bytes in compiled size.

This adds a mutex for fb_mmap around smem_start and smem_len
so the mutex inside the fb_mmap() is actually used. Changing of
these fields before calling the framebuffer_register() are not mutexed.
We check whether framebuffer_register has been called by reading
fbinfo->count.

for details.
