[PATCH] drm/sti: mark symbols static where possible

[PATCH] drm/sti: mark symbols static where possible

[Baoyou Xie]

We get 4 warnings when building kernel with W=1:
drivers/gpu/drm/sti/sti_gdp.c:476:5: warning: no previous prototype for 'sti_gdp_field_cb' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_hqvdp.c:786:5: warning: no previous prototype for 'sti_hqvdp_vtg_cb' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_hqvdp.c:1292:5: warning: no previous prototype for 'sti_hqvdp_bind' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_drv.c:143:6: warning: no previous prototype for 'sti_drm_dbg_cleanup' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

Yeah, I resolved those conflicts by simply taking the code from the sti
tree. I'll send a pull request for drm-misc with that merge to Dave this
week still because I've totally forgotten about Tomeu's work.

Re: [PATCH] drm/sti: mark symbols static where possible

[Benjamin Gaignard]

I think that create conflicts with what is already in Vincent pull
request where we have fix the problem reported by coccicheck and
sparse.

[PATCH] drm/sti: mark symbols static where possible

[Baoyou Xie]

We get 6 warnings when building kernel with W=1:
drivers/gpu/drm/sti/sti_mixer.c:361:6: warning: no previous prototype for 'sti_mixer_set_matrix' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_dvo.c:109:5: warning: no previous prototype for 'dvo_awg_generate_code' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_gdp.c:476:5: warning: no previous prototype for 'sti_gdp_field_cb' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_hqvdp.c:786:5: warning: no previous prototype for 'sti_hqvdp_vtg_cb' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_hqvdp.c:1292:5: warning: no previous prototype for 'sti_hqvdp_bind' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_drv.c:143:6: warning: no previous prototype for 'sti_drm_dbg_cleanup' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

Considering the LOC in the kernel, the number are quite small. Still a
fair bit to go.

Makes perfect sense. Thanks Arnd !

I've looked at the W=1 warnings overall, and the count I got a
month ago was 648 warnings for drivers/gpu/::

    471 -Werror=missing-prototypes
     12 -Werror=type-limits
    124 -Werror=unused-but-set-variable
     41 -Werror=unused-const-variable=

vs for the whole kernel

   2033 -Werror=missing-prototypes
     58 -Werror=suggest-attribute=format
    167 -Werror=type-limits
   1398 -Werror=unused-but-set-variable
   1526 -Werror=unused-const-variable=

but that was after I had already fixed some of the other warnings
locally. It shouldn't be hard to fix all of them for any given
subsystem, often a single line change gets rid of a number
of individual warnings.

My basic idea however is not to do it by subsystem but instead
do it one warning at a time for the entire kernel and then enable
that warning by default without W=1.

> Hope you'll have the time/interest to sort some of the W>1 ones as well 

I suggested to Baoyou that he starts looking at missing-prototype
warnings across the kernel, as these are likely to find the most
actual bugs out of the W=1 warnings we get.

[PATCH] drm/sti: mark symbols static where possible

[Baoyou Xie]

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/sti/sti_mixer.c:361:6: warning: no previous prototype for 'sti_mixer_set_matrix' [-Wmissing-prototypes]
drivers/gpu/drm/sti/sti_dvo.c:109:5: warning: no previous prototype for 'dvo_awg_generate_code' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.
