Jia-Ju Bai be826ada52 char: pcmcia: cm4000_cs: Replace mdelay with usleep_range in set_protocol ... set_protocol() is never called in atomic context. The call chains ending up at set_protocol() are: [1] set_protocol() <- monitor_card() [2] set_protocol() <- cmm_ioctl() monitor_card() is only set in setup_timer(), and cmm_ioctl() is only set as ".unlocked_ioctl" in file_operations structure "cm4000_fops". Despite never getting called from atomic context, set_protocol() calls mdelay(10), i.e. busy wait for 10ms. That is not necessary and can be replaced with usleep_range to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself.
