====

The first error, "implicit declaration of function ‘init_timer’" seems to be
caused by the following upstream kernel commit:

====
commit 7eeb6b893bd28c68b6d664de1d3120e49b855cdb

    timer: Remove init_timer() interface

    All users of init_timer() have been updated. Remove the ancient interface.
