From: David Howells Date: Fri, 12 Apr 2013 01:59:48 +0000 (+0100) Subject: rtl8187se: Use a dir under /proc/net/r8180/ X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c4558a26ff661b5299942ce2b735f3cab4aed1e5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git rtl8187se: Use a dir under /proc/net/r8180/ Create a dir under /proc/net/r8180/ named for the device and create that device's files under there. This means that there won't be a problem for multiple devices in the system (if such is possible) and it means we don't need to save the 'device directory' PDE any more as we can just do a proc subtree removal.
