Subject: [PATCH] USB: net2280: Handle STALLs for 0-length control-IN requests
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a29fccd7993a3d411674e148cb0759a017be3e21;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] USB: net2280: Handle STALLs for 0-length control-IN requests

This patch (as668) fixes a typo in net2280.  The handler for 0-length
control-IN requests should check that the endpoint _isn't_ halted before
sending a 0-length packet.
