Subject: USB: pxa27x_udc: use four bits to store endpoint addresses
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ff8d1b3c858ea7c8daa54f7577971a76d04d283;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

USB: pxa27x_udc: use four bits to store endpoint addresses

Endpoint addresses on pxa27x can be programmed as 1-15, but since
only three bits were being used to store the endpoint number it
was possible to overflow.
