[PATCH 00/17] staging: tidspbridge: remove unused references counting

[Víctor Manuel Jáquez Leal]

Almos all the modules in tidspbridge have a _init() and a _exit()
functions, whose only purpose is to keep a reference counting. But that
reference counting, in most of the cases, is utterly useless.

This patch series removes most of the _init() and _exit() function in
the tidspbridge modules, where no functional changes were implied.

[PATCH 05/17] staging: tidspbridge: remove disp_init() and disp_exit()

[Víctor Manuel Jáquez Leal]

The disp module has a disp_init() and a disp_exit() whose only purpose
is to keep a reference counting which is not used at all.

This patch removes these functions and the reference count variable.

There is no functional changes.

[PATCH 11/17] staging: tidspbridge: remove cmm_init() and cmm_exit()

[PATCH 16/17] staging: tidspbridge: remove ref counting in nldr.c

[Víctor Manuel Jáquez Leal]

The nldr module has a nldr_init() and a nldr_exit() whose only purpose
is to keep a reference counting which is not used at all.

This patch only removes the reference count variable, but not the
functions, because they are used through an interface.

There is no functional changes.

[PATCH 17/17] staging: tidspbridge: remove nldr_init() and nldr_exit()

[Víctor Manuel Jáquez Leal]

The dynamic loader was called by node.c with an interface. This interface was
also modified to avoid the use of nldr_init() and nldr_exit().

There is not functional changes.
