From: David Vrabel Date: Wed, 14 Oct 2009 13:23:55 +0000 (+0000) Subject: USB: whci-hcd: fix type and format warnings in sg code X-Git-Tag: v2.6.33-rc1~315^2~111 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0ad073f043b5ac04620bb80ecfc92114d348044;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git USB: whci-hcd: fix type and format warnings in sg code Fix type and format warning in the new sg code. Remove the very chatty debug messages that were left in by mistake and use min_t() as required (no one seems to agree on a type for buffer sizes).
