Subject: [PATCH] 8390 Tx fix for non i386 machines
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9389d79fbf9a0167ff2de87e8796c6bb803219bf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] 8390 Tx fix for non i386 machines

While this is true, E8390_CMD is zero on i386, and thus there should be no
effect for these machines.  Machines like Mac, Amiga etc. which use Alan's
clever register mapping may have a non-zero E8390_CMD and result in bogus
"transmitter busy" type messages from this bug.

Fixes BUG# 3991.
