[PATCH] move file->f_op->open out of mutex (misc_mtx) in misc_open

misc_mtx was used to mutex misc_list. But file->f_op->open may be blocked by downloading firmware in some devices' open. So move file->f_op->open out of mutex (misc_mtx) in misc_open to avoid this block. It also make code more efficiency. Signed-off-by: Zhang Dongxing Signed-off-by: xiaoming wang
