Subject: [PATCH] thermal: mmio: remove some dead code
Date: Wed, 15 May 2019 12:34:21 +0300 [thread overview]
Message-ID: <20190515093420.GC3409@mwanda> (raw)
The platform_get_resource() function doesn't return error pointers, it
returns NULL. The way this is normally done, is that we pass the NULL
resource to devm_ioremap_resource() and then check for errors from that.
See the comment in front of devm_ioremap_resource() for more details.
