[PATCH v6 23/24] thermal/drivers/loongson2: convert to use devm_request*_irq_probe()

From: Pan Chuang
Date: Mon Jun 23 2025 - 08:48:21 EST


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.
