From e24371a6be9c5c00b56607bd425cc409cba75d88 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 11 Oct 2013 11:28:12 -0400 Subject: USB: EHCI: check the right uframes for CSPLIT The check_intr_schedule() routine in ehci-hcd looks at the wrong microframes when checking to see if a full-speed or low-speed interrupt endpoint will fit in the periodic schedule. If the Start-Split transaction is scheduled for microframe N then the Complete-Split transactions get scheduled for microframes N+2, N+3, and N+4. However the code considers N+1, N+2, and N+3 instead. This patch fixes the limits on the "for" loop and also improves the use of whitespace.
