[PATCH] staging: sm750fb: make fixId array const
Posted by Madhumitha Sundar 1 week, 4 days ago
The fixId array contains constant string literals, but the array itself is
currently mutable.

Make the array const so that the compiler can place it in the read-only
data section (.rodata) instead of writable memory.

This fixes a warning detected by checkpatch.pl:
WARNING: static const char * array should probably be static const char * const
