Subject: most: core: use function subsys_initcall()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e56bc06e18dfc8a66180fa369384b36e2ab621a;p=linux.git

most: core: use function subsys_initcall()

This patch replaces function module_init() with subsys_initcall().
It is needed to ensure that the core module of the driver is
initialized before a component tries to register with the core. This
leads to a NULL pointer dereference if the driver is configured as
in-tree.
