From e98fb11ffa0ab8fd3e99a0d8ff7c2bbb7418a834 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Fri, 18 Nov 2016 19:30:33 +0530 Subject: [PATCH] mwifiex: stop checking for NULL drvata/intfdata These are never NULL, so stop making people think they might be. I don't change this for SDIO because SDIO has a racy card-reset handler that reallocates this struct. I'd rather not touch that mess right now.
