usb: gadget: f_gsi: Add handling of SET_CONTROL_LINE_STATE control request (1a8b284e) · Commits · e / devices / android_kernel_xiaomi_markw

CDC control request SET_CONTROL_LINE_STATE was not handled in gsi_setup(). This is needed for RmNet functionality. This led to below warnings seen on the console any time the RmNet function is activated. gsi_setup: inval ctrl req21.22 v0000 i0004 l0 gsi_setup: inval ctrl req21.22 v0001 i0004 l0 So add the support to handle SET_CONTROL_LINE_STATE request.
