From 639e9903c20611772cb38433add6fe2383b9fabf Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 1 Jul 2014 11:41:18 -0600 Subject: usb: ci_udc: don't memalign() struct ci_req allocations struct ci_req is a purely software structure, and needs no specific memory alignment. Hence, allocate it with calloc() rather than memalign(). The use of memalign() was left-over from when struct ci_req was going to hold the aligned bounce buffer, but this is now dynamically allocated.
