[PATCH v6 08/24] thermal/drivers/renesas/rcar: convert to use devm_request*_irq_probe()

From: Pan Chuang
Date: Mon Jun 23 2025 - 08:42:27 EST


From: Yangtao Li <frank.li@xxxxxxxx>

The new devm_request_*irq_probe API prints an error message by default
when the request fails, and consumers can provide custom error messages.

Converting drivers to use this API has the following benefits:

1.More than 2,000 lines of code can be saved by removing redundant error
messages in drivers.

2.Upper-layer functions can directly return error codes without missing
debugging information.

3.Having proper and consistent information about why the device cannot
be used is useful.
