Subject: Bluetooth: Allow for NULL data in mgmt_pending_add
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8fce6357a9e72c4c9c846f9951895954bfb34ad1;p=linux-beck.git

Bluetooth: Allow for NULL data in mgmt_pending_add

Since index is in mgmt_hdr it is possible to have mgmt command with
no parameters that still needs to add itself to pending list.
