Jia-Ju Bai 9d08ba6de0 media: pci: cx88: Replace mdelay() with msleep() in dvb_register() 
dvb_register() 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.
