[media] pvrusb2: Replace memcpy with struct assignment
Author: Ezequiel Garcia <elezegarcia@gmail.com> This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it’s type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier …

drivers/net/wireless/ti/wlcore/main.c: eliminate possible double power off
Author: Julia Lawall <Julia.Lawall@lip6.fr> The function wl12xx_set_power_on is only called twice, once in wl12xx_chip_wakeup and once in wl12xx_get_hw_info. On the failure of the call in wl12xx_chip_wakeup, the containing function just returns, but on the failure of the call in wl12xx_get_hw_info, the containing function calls wl1271_power_off. This does not seem necessary, because if wl12xx_set_power_on has set …

ALSA: sound/isa/opti9xx/miro.c: eliminate possible double free
Author: Julia Lawall <Julia.Lawall@lip6.fr> snd_miro_probe is a static function that is only called twice in the file that defines it. At each call site, its argument is freed using snd_card_free. Thus, there is no need for snd_miro_probe to call snd_card_free on its argument on any of its error exit paths. Because snd_card_free both reads the …

drivers/iio/industrialio-event.c: eliminate possible double free
Author: Julia Lawall <Julia.Lawall@lip6.fr> The function __iio_add_event_config_attrs is only called once, by the function iio_device_register_eventset. If the call fails, iio_device_register_eventset calls __iio_remove_event_config_attrs. There is thus no need for __iio_add_event_config_attrs to also call __iio_remove_event_config_attrs on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r@ identifier f,free,a; parameter …

powerpc/rtas_flash: Eliminate possible double free
Author: Julia Lawall <Julia.Lawall@lip6.fr> The function initialize_flash_pde_data is only called four times. All four calls are in the function rtas_flash_init, and on the failure of any of the calls, remove_flash_pde is called on the third argument of each of the calls. There is thus no need for initialize_flash_pde_data to call remove_flash_pde on the same argument. …

iio: at91_adc: Use devm_kcalloc to allocate arrays
Author: Lars-Peter Clausen <lars@metafoo.de> Use dev_kcalloc instead of devm_kzalloc to allocate arrays since it is semantically more appropriate. While we are at it the patch also fixes the following coccinelle warning: drivers/iio/adc/at91_adc.c:277:25-31: ERROR: application of sizeof to pointer Signed-off-by: Lars-Peter Clausen Acked-By: Maxime Ripard Signed-off-by: Jonathan Cameron — drivers/iio/adc/at91_adc.c | 16 ++++++———- 1 file changed, …
