From 1b22dcf6b33ace39c11a2832260d499d020c3d55 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Mon, 30 Jul 2018 21:42:56 +0800 Subject: [PATCH] pcmcia: pcmcia_resource: Replace mdelay() with msleep() pcmcia_fixup_iowidth() and pcmcia_enable_device() are never called in atomic context. They call mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself.
