From 5f9492ff1dd7164e3785b9fbd1221fc717efe2c4 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 28 Sep 2016 14:17:38 +0300 Subject: [PATCH] usb: core: endpoint: remove unnecessary & operation Now that usb_endpoint_maxp() only returns the lowest 11 bits from wMaxPacketSize, we can remove the & operation from this driver.
