Re: [PATCH v2 05/10] sysfs: treewide: constify attribute callback of bin_is_visible()
On 03/11/2024 17:03, Thomas Weißschuh wrote:
The is_bin_visible() callbacks should not modify the struct
bin_attribute passed as argument.
Enforce this by marking the argument as const.
As there are not many callback implementers perform this change
throughout the tree at once.
