kernel/generic: Restore kernel files for v6.6
This is an automatically generated commit which aids following Kernel patch
history, as git will see the move and copy as a rename thus defeating the
purpose.

Subject: [PATCH] nvmem: core: drop unnecessary range checks in sysfs callbacks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The same checks have already been done in sysfs_kf_bin_write() and
sysfs_kf_bin_read() just before the callbacks are invoked.
