2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Linus Torvalds <[email protected]> [ Upstream commit caca9510ff4e5d842c0589110243d60927836222 ] In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware. This should fix: https://bugzilla.kernel.org/show_bug.cgi?id=40952 Reported-by: James Cloos <[email protected]> Bisected-by: Elimar Riesebieter <[email protected]> Cc: Michel Dänzer <[email protected]> Cc: Rafael Wysocki <[email protected]> Cc: Valdis Kletnieks <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> Signed-off-by: Srivatsa S.
