From 2e5464da4e7dc55e1751d2beb3e6e78f35020756 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Mon, 27 Jul 2015 12:25:28 +0530 Subject: [PATCH] usb: dwc3: ep0: use _roundup_ to calculate the transfer size No functional change. Used _roundup_ macro to calculate the transfer size aligned to maxpacket in dwc3_ep0_complete_data. It also makes it similar to how transfer size is calculated in __dwc3_ep0_do_control_data.
