| 2018-06-12 | treewide: 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;

| 2016-03-21 | regulator: act8865: Remove "too many regulators" error handler | Maarten ter Huurne | |
| The check would dereference pdata, which can be NULL in the non-DT use case. Nothing will break if pdata->num_regulators is larger than the number of regulators that the driver defines: pdata->num_regulators is only read in act8865_get_init_data() to iterate through pdata->regulators. The error handler might have some value as a sanity check on the platform data, but the platform data could be broken in many other ways that are not checked for (unknown IDs, duplicate IDs), so I see no reason to perform only this specific check.

| 2014-12-01 | of: Rename "poweroff-source" property to "system-power-controller" | Romain Perier | |
| It reverts commit a4b4e0461ec5 ("of: Add standard property for poweroff capability"). As discussed on the mailing list, it makes more sense to rename back to the old established property name, without the vendor prefix. Problem being that the word "source" usually tends to be used for inputs and that is out of control of the OS. The poweroff capability is an output which simply turns the system-power off. Also, this property might be used by drivers which power-off the system and power back on subsequent RTC alarms. This seems to suggest to remove "poweroff" from the property name and to choose "system-power-controller" as the more generic name. This patchs adds the required renaming changes and defines an helper function which checks if this property is set.
