From: Anand Gadiyar Date: Fri, 12 Feb 2010 12:18:59 +0000 (+0530) Subject: USB: ehci: omap: use default interrupt threshold X-Git-Tag: v2.6.34-rc1~215^2~24 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9b43cffbbd3e9f77e16826513f26544cce3b5864;p=platform%2Fkernel%2Flinux-3.10.git USB: ehci: omap: use default interrupt threshold The current driver reduces the interrupt threshold to 1 microframe. This was an accidental change and is not really required. The default of 8 microframes will do just fine. So change it back.
