Subject: [PATCH 0/2] staging: sm750fb: improve error handling in de_wait path
Date: Thu, 9 Apr 2026 14:41:17 +0000 [thread overview]
Message-ID: <20260409144119.21500-1-dennylin0707@gmail.com> (raw)
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.
