Subject: usbtouchscreen: use endpoint address from endpoint descriptor
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8fa59a8f6f7c9a1bc294154fd6805c6b247683d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

usbtouchscreen: use endpoint address from endpoint descriptor

use the endpoint address from the endpoint descriptor instead of the hardcoding
it to 0x81. at least some ITM based screen use a different address and don't work
without this.
