2014-12-02wusb: replace memset by memzero_explicitJulia Lawall
Memset on a local variable may be removed when it is called just before the variable goes out of scope. Using memzero_explicit defeats this optimization. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; type T; @@ { ... when any T x[...]; ... when any when exists - memset + memzero_explicit (x, -0, ...) ... when != x when strict } // </smpl> This change was suggested by Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-12-02xhci: don't use the same variable for stopped and halted rings current TDMathias Nyman
Endpoints halted on errors, and endpoints stopped manually both used the same ep->stopped_td to store the halted or stopped td. this causes confusion and possible races. There is no longer a need to use the ep->stopped_td variable to store the halted TD. A halted endpoint is handled immediately and we can pass it to the handling function directly.

2014-12-02xhci: clear extra bits from slot context when setting max exit latencyMathias Nyman
If we need to change the max exit latency with a Evaluate Context command, we copy the old output slot context and use it as input context for the command. This also copies the dev_state bits which are supposed to be zero in the input slot context.

2014-12-02ext4: fix suboptimal seek_{data,hole} extents traversialDmitry Monakhov
It is ridiculous practice to scan inode block by block, this technique applicable only for old indirect files. This takes significant amount of time for really large files.

2014-12-03drm: rcar-du: Fix NULL encoder pointer dereferenceLaurent Pinchart
The DRM connector's encoder pointer is managed internally by the DRM core and set to NULL when the DRM connector is disconnected from the CRTC it was attached to. This results in a NULL pointer dereference in the HDMI connector functions when trying to call the associated slave encoder's operations. Fix this by retrieving the slave encoder pointer from the R-Car connector structure instead of the DRM connector structure.

2014-12-02NFC: NCI: Fix max length of General Bytes in ATR_RESJulien Lefrique
The maximum size of ATR_REQ and ATR_RES is 64 bytes. The maximum number of General Bytes is calculated by the maximum number of data bytes in the ATR_REQ/ATR_RES, substracted by the number of mandatory data bytes. ATR_REQ: 16 mandatory data bytes, giving a maximum of 48 General Bytes. ATR_RES: 17 mandatory data bytes, giving a maximum of 47 General Bytes. Regression introduced in commit a99903ec.

If there are many inodes that have data blocks in victim segment, it takes long time to find a inode in gc_inode list. Let's use radix_tree to reduce lookup time. Signed-off-by: Changman Lee <cm224.lee@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2014-12-02sata_fsl: fix error handling of irq_of_parse_and_mapDmitry Torokhov
irq_of_parse_and_map() returns 0 on error (the result is unsigned int), so testing for negative result never works. Signed-off-by: Dmitry Torokhov <dtor@chromium.org> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: stable@vger.kernel.org
2014-12-02ALSA: echoaudio: Deletion of a check before release_and_free_resource()Markus Elfring
The release_and_free_resource() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed.

2014-12-02scsi: set fmt to NULL scsi_extd_sense_format() by defaultDan Carpenter
One of the two callers passes an unintialized pointer as "fmt" and expects it to be set to NULL if there is no format string. Let's make this function work as expected.
