[PATCH 0/2] staging: sm750fb: improve error handling in de_wait path

[Hungyu Lin]

This series improves error handling in the sm750fb driver.

The de_wait() helpers currently return -1 on timeout and callers
discard error codes by always returning -1. This series replaces
-1 with -ETIMEDOUT and propagates the error code to improve
error reporting.

Patch 1 replaces -1 with -ETIMEDOUT in de_wait() helpers.
Patch 2 propagates error codes in callers instead of returning -1.
