[PATCH] i2c: qcom-geni: Simplify PM resume error handling

[PATCH] i2c: qcom-geni: Simplify PM resume error handling

[Mukesh Kumar Savaliya]

The driver currently logs pm_runtime_resume_and_get() failures with
dev_err() and returns the error code separately.

Replace this with dev_err_probe(), which combines the dev_err() log
message and the return value propagation into a single call, consistent
with how all other error paths in this driver already report failures.

No functional change intended.

This change is not required, as this API will be used in the deep sleep 
use case to reinitialise the SE.


Thanks,

I think this change is generic and does not appear to introduce any new 
functionality. Its more like a cleanup or modernization that aligns the 
PM handling with the pattern already used in the drivers probe path.

What exactly is getting broken during deep sleep with this change ? 
Could you elaborate on the specific suspend/resume issue that is getting 
disturbed ?
