* leds: Convert all platform drivers to return voidUwe Kleine-König2023-11-011-4/+2
| | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). All platform drivers below drivers/leds/ unconditionally return zero in their remove callback and so can be converted trivially to the variant returning void.

* leds: various: use only available OF childrenMarek Behún2020-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various drivers count and iterate over OF children nodes via of_get_child_count and for_each_child_of_node. Instead they should use of_get_available_child_count and for_each_available_child_of_node, so that if a given node has the `status` property set to `disabled`, the child will be ignored.

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;

* Merge branch 'master' into for-nextJiri Kosina2011-04-261-3/+4
|\ | | | | | | | | Fast-forwarded to current state of Linus' tree as there are patches to be applied for files that didn't exist on the old branch.
| * mfd: mfd_cell is now implicitly available to mc13xxx driversAndres Salomon2011-03-231-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
