Subject: [PATCH v1 0/2] Fix read permissions for VPD attributes

From: Leon Romanovsky <leonro@...dia.com>

Changelog:
v1: 
 * Changed implementation from open-read-to-everyone to be opt-in
 * Removed stable and Fixes tags, as it seems like feature now.
v0: https://lore.kernel.org/all/65791906154e3e5ea12ea49127cf7c707325ca56.1730102428.git.leonro@nvidia.com/

Hi,

The Vital Product Data (VPD) sysfs file is not readable by unprivileged
users. This limitation is not necessary and can be removed at least for
devices which are known as safe.

Thanks
