misc: tifm: fix possible memory leak in tifm_7xx1_switch_media()
[ Upstream commit fd2c930cf6a5b9176382c15f9acb1996e76e25ad ]
If device_register() returns error in tifm_7xx1_switch_media(),
name of kobject which is allocated in dev_set_name() called in device_add()
is leaked.
Never directly free @dev after calling device_register(), even
if it returned an error! Always use put_device() to give up the
reference initialized.
Fixes: 2428a8fe2261 ("tifm: move common device management tasks from tifm_7xx1 to tifm_core")
