[PATCH v6 0/2] drm/panthor: Display size of internal kernel BOs through fdinfo

[Adrián Larumbe]

This patch series enables display of the size of driver-owned shmem BO's that aren't
exposed to userspace through a DRM handle.

Discussion of previous revision can be found here [1].

Changelog:
v6:
 - Replace up_write with up_read, which was left out in the previous version
 - Fixed some minor comment and documentation issues reported by the kernel test robot
v5:
 - Replaced down_write semaphore with the read flavour
 - Fixed typo and added explicit description for drm-shared-internal in
 the fdinfo documentation file for Panthor.
v4:
 - Remove unrelated formating fix
 - Moved calculating overall size of a group's kernel BO's into
 its own static helper.
 - Renamed group kernel BO's size aggregation function to better
 reflect its actual responsibility.
