Subject: wil6210: fix interface-up check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b2a4c2d534ca45c74488bace32323b26633ff66;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

wil6210: fix interface-up check

While wil_open is executed, any call to netif_running
would return a success. In case there are failures
within wil_open, should not treat the device as if it
is already opened in relevant functions (like FW recovery
and runtime suspend check).

Fix that by checking the device up flag instead.
