PM / yenta: Split resume into early and late parts (rev. 4)
Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a listed regression from 2.6.31. Signed-off-by: Rafael J.
