commit 025f880cb2e4d7218d0422d4b07bea1a68959c38 upstream.

usb: gadget: f_mass_storage: add missing memory barrier for thread_wakeup_needed

2013-07-22T01:14:40Z

commit d68c277b501889b3a50c179d1c3d704db7947b83 upstream. Without this memory barrier, the file-storage thread may fail to escape from the following while loop, because it may observe new common->thread_wakeup_needed and old bh->state which are updated by the callback functions. /* Wait for the CBW to arrive */ while (bh->state != BUF_STATE_FULL) { rc = sleep_thread(common); if (rc) return rc; } Signed-off-by: UCHINO Satoshi Acked-by: Michal Nazarewicz Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

2013-07-22T01:14:40Z

commit a254810a86aaaac4ac6ba44fa934558b042a17a7 upstream. These devices are all Gobi1K devices (according to the Windows INF files) and should be handled by qcserial instead of option. Their network port is handled by qmi_wwan. Signed-off-by: Dan Williams Signed-off-by: Greg Kroah-Hartman

USB: revert periodic scheduling bugfix

2013-06-13T16:25:04Z

commit fdc03438f53a00294ed9939eb3a1f6db6f3d8963 upstream. This patch reverts commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d (USB: EHCI: fix bug in scheduling periodic split transfers). The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project... This fixes https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110. Thanks to Tim Richardson for extra testing and feedback, and to Joseph Salisbury and Tyson Tan for tracking down the original source of the problem.
