From: Mark Greer Date: Tue, 25 Apr 2017 22:43:51 +0000 (-0700) Subject: NFC: trf7970a: Only check 'en2-rf-quirk' if EN2 is specified X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=afcb9fbdba71cd39daefaff1e288472565df6af2;p=openwrt%2Fstaging%2Fblogic.git NFC: trf7970a: Only check 'en2-rf-quirk' if EN2 is specified The quirk indicated by the 'en2-rf-quirk' device tree property is only relevant when there is a GPIO connected to the EN2 pin of the trf7970a. This means we should only check for 'en2-rf-quirk' when EN2 is specified in the 'ti,enable-gpios' property of the device tree.
