From 4256101f8ca908438ddbb5bd649274dbfd936f22 Mon Sep 17 00:00:00 2001 From: Igor Grinberg Date: Mon, 12 Dec 2011 12:08:33 +0200 Subject: [PATCH] USB: ULPI: clean a mixup of return types Clean a mixup between u32 and int as a return type for functions returning error values. Use int as it is native (and widely used) return type.
