From: Cornelia Huck Date: Tue, 17 Apr 2007 11:01:38 +0000 (+0200) Subject: qeth: Remove usage of subsys.rwsem X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2f66858a0ae48faf4c8dc19042f3aff52208dc57;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git qeth: Remove usage of subsys.rwsem the current driver tree contains the removal of subsys.rwsem. Unfortunately, this breaks qeth. However, it should be no problem to fix the walking of the devices for /proc/qeth: No need to take subsys.rwsem during walking the devices, driver_find_devices() should already suffice.
