Subject: NFC: st-nci: Add error messages when an unexpected HCI event occurs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2b5dbe089f619f995faf2fe6beb7efb705eed302;p=linux-beck.git

NFC: st-nci: Add error messages when an unexpected HCI event occurs

Potentially an unexpected HCI event may occur because of a
firmware bug. It could be transparent for the user but we need to
at least log it.
