Subject: DM9000: Remove old timer based poll routines
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcfa81aa3e8d885356139122fcb281487b983468;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

DM9000: Remove old timer based poll routines

Remove the timer based MII phy polling, as this is
currently broken with the new EEPROM code that now
uses mutexes to protect the phy access.

This will need to be replaced in the future by some
form of mutex safe mechanism for reading the MII
phy status.

The replacement has not been done here as changing
this patch, which is early in the sequence has quite
a knock-on effect. Once this series is merged, then
a new presentation of an patch to poll the MII link
status can be added.
