From: Johannes Berg Date: Mon, 6 Mar 2017 14:49:00 +0000 (+0100) Subject: iwlwifi: pcie: apply no-reclaim logic only to group 0 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8a130b02d0caa9a8f0c14db11d84320ffc62c57;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: pcie: apply no-reclaim logic only to group 0 When applying no-reclaim logic to commands other than the group zero for legacy commands, commands such as 0x1c (TX_CMD in group 0) can't be used in any other group. Fix that by applying this logic only for group 0 - it's not and should never be needed for any other groups.
