Linus Torvalds e0d5fa9ae4 ubi: use put_user() when filling the erase counter array 
ubi_get_ec_info() checks the user's erase_counters array with
access_ok() and then fills it one entry at a time with __put_user(),
taking the wear-leveling lock for each entry in between.  Each of those
accesses enables and disables user access on its own, so the up-front
check saves nothing.

Use put_user().  The access_ok() stays, so a bad array still fails
before anything is written.

This is part of getting rid of __get_user() and __put_user() entirely.
