2014-05-25staging: rtl8712: remove _malloc()Vitaly Osipov
This patch removes all usage of _malloc() and the function itself. Most uses are straightforward replacements by kmalloc(..., GFP_ATOMIC), because this was the definition of _malloc(). In a few places it was possible to use kzalloc() or memdup_user. A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL where possible. Verified by compilation only. Initial replacement done by running a Coccinelle script along the lines of: @@ type T; expression E; identifier V; @@ - V = (T) _malloc(E); + V = kmalloc(E, GFP_ATOMIC); @@ expression E, E1; @@ - E1 = _malloc(E); + E1 = kmalloc(E, GFP_ATOMIC); Signed-off-by: Vitaly Osipov <vitaly.osipov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third round of new stuff for IIO in the 3.16 cycle. This (rather late) set consists only of fixes to patches earlier in the cycle or minor fixes for other problems (such as randconfig build issues picked up by Arnd). I've included the general minor fixes here as it is very late in the current cycle and they can all wait for the merge window. * Recent change to hid-sensors introduced a possible infinite loop due to a typo. In the same series, a report interval unit read was added but in the case where the hardware doesn't support it a value of 0 would lead to some nasty issues. The patch sets it to the specified default of msecs. * Anon inodes were used by IIO without being explicitly selected. This has been true for a long time so it clearly only effects rather unusual configurations (rand configs) * at91 requires the input subsytem but this wasn't explicity in the Kconfig. * A couple of parts supported by the max1363 driver were using the wrong iio_chan_spec arrays and hence would missreport their bit depths. This has been there a long time and was never right so isn't a regression.

2014-05-25[media] adv7604: Replace *_and_or() functions with *_clr_set()Laurent Pinchart
The *_and_or() functions take an 'and' bitmask to be ANDed with the register value before ORing it with th 'or' bitmask. As the functions are used to mask and set bits selectively, this requires the caller to invert the 'and' bitmask and is thus error prone. Replace those functions with a *_clr_set() variant that takes a mask of bits to be cleared instead of a mask of bits to be kept.
