From: Mark Brown Date: Fri, 5 Jul 2013 10:24:26 +0000 (+0100) Subject: spi/xilinx: Refer to platform device as pdev in probe() and remove() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7cb2abd05fe1f9aea70b8ee38004b60bc882ffb5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git spi/xilinx: Refer to platform device as pdev in probe() and remove() This is a more traditional name and makes things a bit clearer when referring to actual struct devices as we do frequently during probe().
