Colin Ian King 0eeea4b8f0 libertas_tf: avoid a null dereference in pointer priv ... [ Upstream commit 049ceac308 ] Currently there is a check if priv is null when calling lbtf_remove_card but not in a previous call to if_usb_reset_dev that can also dereference priv. Fix this by also only calling lbtf_remove_card if priv is null. It is noteable that there don't seem to be any bugs reported that the null pointer dereference has ever occurred, so I'm not sure if the null check is required, but since we're doing a null check anyway it should be done for both function calls.
