Revert "USB: isp1760-hcd: move imask clear after pending work is done"
This reverts commit 5808544690300071f09eef9ab83a0fb1f60cf1cd. To quote Richard: I don't think this should be mainlined. It was a misunderstanding on my part. If you see all the other hdc drivers in the same location, they all do the same thing (i.e. clear the interrupt status first, then do the work) that "glitch" I think I saw was actually two back-to-back interrupts. Sebastian (the original author of isp1760) explained it to me a few days after my submission. sorry for the confusion Cc: Richard Retanubun <RichardRetanubun@ruggedcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
