Subject: wl12xx: move ps_poll_failures and psm_entry_retry into wlvif
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=74ec839557878007c3f97d1bc89e09fde5d0f3fa;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

wl12xx: move ps_poll_failures and psm_entry_retry into wlvif

move ps_poll_failures and psm_entry_retries into the per-interface
data, rather than being global.
