mmc: sdhci: fix NULL dereference in sdhci_request() tuning

2012-11-17T21:19:05+00:00

commit 14efd957209461bbdf285bf0d67e931955d04a4c upstream.

Commit 473b095a72a9 ("mmc: sdhci: fix incorrect command used in tuning")
introduced a NULL dereference at resume-time if an SD 3.0 host controller
raises the SDHCI_NEEDS_TUNING flag while no card is inserted.  Seen on an
OLPC XO-4 with sdhci-pxav3, but presumably affects other controllers too.

mmc: sh_mmcif: fix use after free

2012-11-17T21:19:05+00:00

commit a0d28ba01ebd048b4ba418142b37f5cf80e6d156 upstream.

A recent commit "mmc: sh_mmcif: fix clock management" has introduced a
use after free bug in sh_mmcif.c: in sh_mmcif_remove() the call to
mmc_free_host() frees private driver data, therefore using it afterwards
is a bug. Revert that hunk.

drivers/net/ethernet/nxp/lpc_eth.c: Call mdiobus_unregister before mdiobus_free

[ Upstream commit 57c10b61c84bfed68b1b317d6f507a392724b9c4 ]

Based on commit b27393aecf66199f5ddad37c302d3e0cfadbe6c0

Calling mdiobus_free without calling mdiobus_unregister causes
BUG_ON(). This patch fixes the issue.

net: usb: Fix memory leak on Tx data path

2012-11-17T21:18:52+00:00

[ Upstream commit 39707c2a3ba5011038b363f84d37c8a98d2d9db1 ]

Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor()
unanchors the urb but urb reference count remains same.
This causes the urb reference count to remain non-zero
after usb_free_urb() gets called and urb never gets freed.
Hence call usb_put_urb() after anchoring the urb to properly
balance the reference count for these deferred urbs. Also,
unanchor these deferred urbs during disconnect, to free them
up.

commit 3300fb4f88688029fff8dfb9ec0734f6e4cba3e7 upstream.

Don't assume bank 0 is selected at device probe time. This may not be
the case. Force bank selection at first register access to guarantee
that we read the right registers upon driver loading.

drm: set dev_mapping before calling drm_open_helper

2012-11-17T21:18:49+00:00

commit fdb40a08ef7bc970899c3a1f471165f9c22763a1 upstream.

Some drivers (specifically vmwgfx) look at dev_mapping
in their open hook, so we have to set dev->dev_mapping
earlier in the process.
