Subject: [PATCH 2/2] mmc: meson-mx-sdio: Cleanup IS_ERR() checks
Date: Fri, 13 Oct 2017 14:20:49 +0300	[thread overview]
Message-ID: <20171013112049.rdcdqv6ooktlv5wz@mwanda> (raw)
In-Reply-To: <20171013111943.zyp5myiwb3pp56vh@mwanda>

Using PTR_ERR_OR_ZERO() instead of IS_ERR() works, but it's not how
you're supposed to write these conditions.

I really hope it doesn't become a trend on to wrap all error checks in a
WARN_ON() macro...
