Subject: pcmcia: at91_cf: Use PTR_ERR_OR_ZERO()
X-Git-Tag: v4.16-rc1~98^2~16^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1203839290f151b84f5e54165d6d039e9514b236;p=thirdparty%2Fkernel%2Flinux.git

pcmcia: at91_cf: Use PTR_ERR_OR_ZERO()

Fix ptr_ret.cocci warnings:
drivers/pcmcia/at91_cf.c:239:1-3: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR
