Subject: [PATCH -next v2] remoteproc: stm32: Clean up redundant dev_err_probe()
Date: Thu, 17 Aug 2023 16:33:36 +0800	[thread overview]
Message-ID: <20230817083336.404635-1-chenjiahao16@huawei.com> (raw)

Referring to platform_get_irq()'s definition, the return value has
already been checked if ret < 0, and printed via dev_err_probe().
Calling dev_err_probe() one more time outside platform_get_irq()
is obviously redundant. Removing outside dev_err_probe() to
clean it up.

Besides, switch to use platform_get_irq_optional() since the irq
is optional here.
