From: Sarah Sharp Date: Fri, 2 Sep 2011 18:05:56 +0000 (-0700) Subject: xhci: Don't print short isoc packets. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fd984d242afbe13bd94c60b6754feda93be69bd7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git xhci: Don't print short isoc packets. Now that the xHCI driver always return a status value of zero for isochronous URBs, when the last TD of an isochronous URB is short, the local variable "status" stays set to -EINPROGRESS. When xHCI driver debugging is turned on, this causes the log file to fill with messages like this: [ 38.859282] xhci_hcd 0000:00:14.0: Giveback URB ffff88013ad47800, len = 1408, expected = 580, status = -115 Don't print out the status of an URB for isochronous URBs.
