Subject: Bluetooth: Fix missing NULL check for smp_chan_create() return value
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c29d2444170a4e0709331e357a2738a02666a633;p=linux-beck.git

Bluetooth: Fix missing NULL check for smp_chan_create() return value

The smp_chan_create function may return NULL, e.g. in the case of memory
allocation failure, so we always need to check for this.
