[PATCH 5.3 157/197] xtensa: fix change_bit in exclusive access option

[Greg Kroah-Hartman]

From: Max Filippov <jcmvbkbc@xxxxxxxxx>

commit 775fd6bfefc66a8c33e91dd9687ed530643b954d upstream.

change_bit implementation for XCHAL_HAVE_EXCLUSIVE case changes all bits
except the one required due to copy-paste error from clear_bit.
