From e90ed12cc4388d2919823fb31368781baa6dfbe5 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 4 Jun 2011 09:10:21 +0300 Subject: [PATCH] USB: wusbcore: return negative error codes cbaf_cdid_get() is only used in cbaf_wusb_chid_store(). In the original code cbaf_cdid_get() returns either a negative error code or a small positive value on error. I have changed it to return -ENOENT if there is not enough data available. In the original code the caller changed the negative error codes to positive return values. I've changed it to just return the error value directly.
