Subject: [PATCH] b44: check link state during open
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e254e9bff5283aad1af6d74d2a312ee011b84d61;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] b44: check link state during open

Check the link state during b44_open.  This closes a 1 HZ window
that existed after b44_open ran but before the b44_timer handler ran,
during which ethtool would report "Link detected: yes" no matter what
the link state actually was.
