Subject: [PATCH] platform/x86: intel_mid_powerbtn: fix error return code in mid_pb_probe()
Date: Wed, 9 Aug 2017 11:00:54 -0500 [thread overview]
Message-ID: <20170809160054.GA27501@embeddedgus> (raw)
platform_get_irq() returns an error code, but the intel_mid_powerbtn
driver ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Print error message and propagate the return value of platform_get_irq
on failure.
This issue was detected with the help of Coccinelle.
