staging: sm750fb: return -ETIMEDOUT on timeout in de_wait functions

Browse source

The hw_sm750le_de_wait() and hw_sm750_de_wait() functions return -1
when a timeout occurs. Replace these with -ETIMEDOUT to use a proper
errno value and better describe the error condition.

All callers check the return value as non-zero, so this change does
not alter existing behavior.
