From ccb2ca78a7278ec0024f281fdc2155b32f995cef Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Thu, 26 Jul 2018 23:09:46 -0400 Subject: [PATCH] media: pci: cx23885: Replace mdelay() with msleep() and usleep_range() in altera_ci_slot_reset() altera_ci_slot_reset() is never called in atomic context. It calls 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.
