[PATCH] clocksource/drivers/timer-ti-dm: Remove omap_dm_timer_set_load_start

[PATCH] clocksource/drivers/timer-ti-dm: Remove omap_dm_timer_set_load_start

[Nathan Chancellor]

Commit 008258d995a6 ("clocksource/drivers/timer-ti-dm: Make
omap_dm_timer_set_load_start() static") made omap_dm_time_set_load_start
static because its prototype was not defined in a header. Unfortunately,
this causes a build warning on multi_v7_defconfig because this function
is not used anywhere in this translation unit:

drivers/clocksource/timer-ti-dm.c:589:12: error: unused function
'omap_dm_timer_set_load_start' [-Werror,-Wunused-function]

In fact, omap_dm_timer_set_load_start hasn't been used anywhere since
commit f190be7f39a5 ("staging: tidspbridge: remove driver") and the
prototype was removed in commit 592ea6bd1fad ("clocksource: timer-ti-dm:
Make unexported functions static"), which is probably where this should
have happened.

Fixes: 592ea6bd1fad ("clocksource: timer-ti-dm: Make unexported functions static")
Fixes: 008258d995a6 ("clocksource/drivers/timer-ti-dm: Make omap_dm_timer_set_load_start() static")

My apologies if this has already been sent, I didn't see anything in tip

Alternatively you might want to look at "clocksource: timer-ti-dm: Add event
capture": https://patchwork.kernel.org/patch/10237217/ (it makes use of
function being removed here). It is a part of an attempt to add event capture
for OMAP. Of course I would like this functionality to be implemented, but
as I do not have a time to continue, I cannot really object removing this
function.

Just in case you'd be interested in finishing this task ;-)

Well seems like no other takers :) We can always find the missing
function in git history when needed, so I suggest we apply this.

Adding Keerthy to Cc as he just posted a similar patch.

Hi Tony,

can you ask for an acked-by before pulling a patch in your tree?

I certainly do ask and wait for acks where possible :)

Note that I have not applied this patch. I just added
Keerthy to Cc on this thread so maybe you misread the
message earlier. My comment "seems like no other
takers" was for Ladislav regarding somebody picking up
his earlier work, not for picking up this patch :)

In any case, I've been waiting for you guys to pick up
the patch, here's my ack if you're waiting for it:

Actually I was referring to the commit 592ea6bd1fad. Anyway as stated
above I could have miss your call.

The patch does not apply. Is it aligned with tip/timers/core ?

The commit this fixes is in timers/urgent and it doesn't look like that
has been backmerged into timers/core.

I can see those fixes in timers/core:

Fixes: 592ea6bd1fad ("clocksource: timer-ti-dm: Make unexported
functions static")
Fixes: 008258d995a6 ("clocksource/drivers/timer-ti-dm: Make
omap_dm_timer_set_load_start() static")


Are you referring to another fix?

Anyway, probably simple to apply it directly to timers/urgent then.
That's good I have other patches for the branch.

Hmm so this one was over a year ago related to the PWM series :)

Seems the warnings started with this one.

Hmm so commit 592ea6bd1fad was part of the PWM timer series
that was posted several times from late 2017 to end of
February 2018. I did not get any timer related acks or
comments so I applied it together with the PWM timer
changes.

I'm guessing you may have accidentally checked out some
older deja-vu branch from about a year ago? Commit
592ea6bd1fad is not related to this fix.. :)

Tony

Just for the record, I said this patch fixes 592ea6bd1fad because
592ea6bd1fad should have been marked this function as static, which
would have exposed that this function was unused and it could have
been removed at that time. I know it is a bit of a stretch for this
commit (would be more appropriate for 008258d995a6 to have it) but
that was my logic behind it. Not opposed to having it removed before
committing.

Nathan

Oh OK yes they should have all become static with the PWM
series.
