Subject: [PATCH] Make PC300 WAN driver compile again
X-Git-Tag: MMI-PSA29.97-13-9~46739^2~17
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8aca23103c2ed2cf158adbe92f4f17ee69463d1a;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

[PATCH] Make PC300 WAN driver compile again

This patch removes accesses to the HDLC-internal data structures
from pc300 driver, thus enabling it to compile but breaking part
of its functionality.
