ata: pata_pdc2027x: Replace mdelay with msleep
After checking all possible call chains to pdc_adjust_pll and pdc_detect_pll_input_clock, my tool finds that these functions are never called in atomic context, namely never in an interrupt handler or holding a spinlock. And their caller functions pdc2027x_init_one and pdc2027x_reinit_one calls pci_enable_device which can sleep, and no spinlock is held when calling pdc_adjust_pll and pdc_detect_pll_input_clock, so it proves that pdc_adjust_pll and pdc_detect_pll_input_clock can call functions which can sleep. Thus mdelay can be replaced with msleep to avoid busy wait. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
