Subject: iwlwifi: mvm: change the check for ADD_STA status
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=837c4da98481d4e504b2aba077c8528fee1b6d13;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iwlwifi: mvm: change the check for ADD_STA status

The firmware will return the baid for BA session in the
ADD_STA command response.
This requires masking the check of the status, which is
actually only 8 bits, and not the whole 32 bits.
