[PATCH v3] staging: sm750fb: Keep g_fbmode array non-const
Posted by Chhabilal Dangal 1 month ago
The g_fbmode array is modified at runtime, so it must remain
non-const. Added clarifying comment.

No comment is needed, if you change the code, it breaks the build, so
that is very obvious as you would never submit a patch that you did not
