[PATCH] staging: gdm724x: make DEVICE_STRING array const

From: pdsj2807

Date: Thu Oct 15 2026 - 05:37:23 EST


From: Palak Raval <pdsj2807@xxxxxxxxx>

The DEVICE_STRING array contains pointers to string literals and is
never modified.

Declare it as 'const char * const' to improve const correctness and
prevent accidental modification. Also fix minor formatting issues
reported by checkpatch.

No functional changes intended.
