lock_kernel used in musb drivers

Hi All,

I observed in /linux/drivers/usb/musb/ musb_hset.c and skeleton_usb.c files lock_kernel() and unlock_kernel() is used.
Can we replace this with spinlock to protect critical section ?
I tried this and require more inputs from Linux Kernel Experts.

Thanks & Regards,
