Hi Ahmet,

Thank you for the review.

I compiled the patch with CONFIG_FB_SM750 enabled and it fails
with the following errors:

sm750.c:773: error: assignment of read-only location 'g_fbmode[index]'
sm750.c:775: error: assignment of read-only location 'g_fbmode[index]'
sm750.c:884: error: assignment of read-only location 'g_fbmode[0]'
sm750.c:888: error: assignment of read-only location 'g_fbmode[1]'

The array elements are assigned at runtime in lynxfb_set_fbinfo()
and sm750fb_setup(), so making them const is incorrect.
The checkpatch warning is a false positive in this case.

I will drop this patch.

Regards,
suryasaimadhu

Make g_fbmode a constant pointer array by adding const qualifier
after the asterisk, as recommended by checkpatch.

Did you compile this patch while sm750fb module is enabled?
