[PATCH v2 0/2] staging: sm750fb: improve error handling in de_wait path

Posted by Hungyu Lin 2 months ago

This series improves error handling in the sm750fb driver.

The de_wait() helpers previously returned -1 on timeout, and
callers discarded the error code 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 from de_wait().

v2:
- Restore the removed comment in sm750_accel.c as requested
