Subject: Re: [PATCH v1 4/4] Bluetooth: hci_qca: Add HCI command timeout
handling
Hi Rocky,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on bluetooth-next/master]
[also build test WARNING on linux/master linus/master v5.5-rc3 next-20191220]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

base: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git master
reproduce:
# apt-get install sparse
