Drop call to of_match_device, which is subsumed by the subsequent call to of_device_get_match_data. The code becomes simpler, and a temporary variable can be dropped. The semantic match that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ local idexpression match; identifier i; expression x, dev, e, e1; @@ - match@i = of_match_device(x, dev); - if (match) e = of_device_get_match_data(dev); - else e = e1; + e = of_device_get_match_data(dev); + if (!e) e = e1; @@ identifier r.i; @@ - const struct of_device_id *i; ... when != i // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-06-12treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

In kernel version 3.13, devm_regulator_get() may return no error if a regulator is undeclared. regulator_get_voltage() will return -EINVAL if this happens.

2013-02-02iio/adc: (max1363) Fix data conversion problemsGuenter Roeck
For chips with more than 8 bit ADC resolution, received data was always masked against 0xfff, ie with a 12 bit mask. This can result in bad data for chips with 10 bit resolution if those chips have higher bits set (seen with MAX1139). The receive buffer was defined as char array. This could result in unintentional sign extensions if the upper bit in a received byte was set. Since the chip is configured for unipolar mode, we never have to handle negative values, and sign extensions are never needed.

2013-01-07Merge branch 'staging-linus' into staging-nextGreg Kroah-Hartman
This is to get the comedi fixes, and resolve the issue in comdi_test.c and comedi_fops.c that were caused by changes in both branches. It also allows the fwserial driver changes to be applied, as they required the fixes that are in staging-linus. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-27iio: (max1363) Fix probe error pathGuenter Roeck
Instantiating the driver with no available regulator results in: [39711.686393] i2c i2c-7: new_device: Instantiated device max1139 at 0x35 [39711.688687] BUG: unable to handle kernel paging request at fffffffffffffe13 [39711.688734] IP: [<ffffffff813e835b>] regulator_disable+0x1b/0x80 [39711.688788] PGD 1c0e067 PUD 1c0f067 PMD 0 [39711.688835] Oops: 0000 [#1] SMP Caused by bad probe error path. Fix it. Driver should also not attempt to free the interrupt in its error path if none was allocated. Fix that problem as well. Finally, testing if the regulator was allocated is not necessary in the remove function, since the probe function bails out if this is the case. Remove that check.
