staging: comedi: 8255_pci: initialize MITE data window

2014-05-05T12:24:37Z

commit 268d1e799663b795cba15c64f5d29407786a9dd4 upstream. According to National Instruments' PCI-DIO-96/PXI-6508/PCI-6503 User Manual, the physical address in PCI BAR1 needs to be OR'ed with 0x80 and written to register offset 0xC0 in the "MITE" registers (BAR0). Do so during initialization of the National Instruments boards handled by the "8255_pci" driver. The boards were previously handled by the "ni_pcidio" driver, where the initialization was done by `mite_setup()` in the "mite" module. The "mite" module comes with too much extra baggage for the "8255_pci" driver to deal with so use a local, simpler initialization function. Signed-off-by: Ian Abbott Signed-off-by: Jiri Slaby

zram: avoid null access when fail to alloc meta

2014-03-22T21:01:47Z

commit db5d711e2db776f18219b033e5dc4fb7e4264dd7 upstream. zram_meta_alloc could fail so caller should check it. Otherwise, your system will hang. Signed-off-by: Minchan Kim Acked-by: Jerome Marchand Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Jiri Slaby

commit 260ea9c2e2d330303163e286ab01b66dbcfe3a6f upstream. The D-Link DWA-123 REV D1 with USB ID 2001:3310 uses this driver. Signed-off-by: Manu Gupta Signed-off-by: Larry Finger Signed-off-by: Jiri Slaby

staging: binder: Fix death notifications

2014-03-05T16:13:50Z

commit e194fd8a5d8e0a7eeed239a8534460724b62fe2d upstream. The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the node release code to a separate function broke death notifications in some cases. When it encountered a reference without a death notification request, it would skip looking at the remaining references, and therefore fail to send death notifications for them.

staging: comedi: adv_pci1710: fix analog output readback value

2014-02-22T21:32:27Z

commit 1e85c1ea1ff2a60659e790ef8ec76c7339445841 upstream. The last value written to a analog output channel is cached in the private data of this driver for readback. Currently, the wrong value is cached in the (*insn_write) functions. The current code stores the data[n] value for readback afer the loop has written all the values. At this time 'n' points past the end of the data array. Fix the functions by using a local variable to hold the data being written to the analog output channel. This variable is then used after the loop is complete to store the readback value. The current value is retrieved before the loop in case no values are actually written..

staging: r8188eu: Fix typo in USB_DEVICE list

2014-02-22T21:32:26Z

commit 08951f10ae146d0c4114ac508310ad316b6f8798 upstream. There is a typo in the device list that interchanges the vendor and product codes for one of the entries. This exchange was determined by noticing that the vendor code is 0x07b8 for Abocom at http://www.linux-usb.org/usb.ids. Signed-off-by: Larry Finger Signed-off-by: Greg Kroah-Hartman

staging: lustre: fix quotactl permission denied (LU-4530)

2014-02-22T21:32:26Z

commit 8b9e418c013e8b671fc10108ab14243f0657bffd upstream. The changes introduced in commit 4b1a25f06b30b203 ("fix build when CONFIG_UIDGID_STRICT_TYPE_CHECKS is on") got the UID check the wrong way around, leading to "Permission denied" when a regular user attempts to retrieve his quota (lfs quota -u ...) but allowing him to retrieve other users quota.

zram: fix race between reset and flushing pending work

2014-02-06T19:22:19Z

commit da4a04126baa3be03bc566d4a2ee0944c5e783d0 upstream. Dan and Sergey reported that there is a racy between reset and flushing of pending work so that it could make oops by freeing zram->meta in reset while zram_slot_free can access zram->meta if new request is adding during the race window. This patch moves flush after taking init_lock so it prevents new request so that it closes the race.
