V4L/DVB (9912): em28xx: fix/improve em28xx locking schema Changes/fixes on em28xx dev->lock: - em28xx_init_dev() were unlocking without a previous lock; - some read ioctls need to lock after the removal of KBL, since a write may be happening at the same time an ioctl is reading; - keep the device locked during all device initialization; - lock/unlock while reading/writing registers.
