while working on an extension for the pwm framework, I noticed that some
drivers and even the core only nearly consistently named all variables
and struct members holding a pointer to a struct pwm_chip "chip":

$ git grep -Pho 'struct pwm_chip \**[a-z0-9_]+(*nla:[\(a-z0-9_])' v6.5-rc1 | sort | uniq -c | sort -n
      1 struct pwm_chip *pwm
      1 struct pwm_chip pwm
      1 struct pwm_chip pwm_chip
      2 struct pwm_chip *_chip
      4 struct pwm_chip *c
      8 struct pwm_chip *pc
     57 struct pwm_chip chip
    358 struct pwm_chip *chip

With this series applied these are all called "chip" with one exception:
The led driver drivers/leds/rgb/leds-qcom-lpg.c uses "pwm". Maybe
"pwmchip" would be a better name, but I'm not sure that using "chip" was
an improvement there as this isn't a pure pwm driver. I'm not touching
that one.

The first offenders I found were the core and the atmel-hlcdc driver.
After I found these I optimistically assumed these were the only ones
with the unusual names and send patches for these out individually
before checking systematically.

The atmel-hlcdc patch is included here unchanged, the core patch now
also adapted the declaration of the changed functions in <linux/pwm.h>.
I marked these two as "superseded" in patchwork already.

All patches in this series are pairwise independent of each other. I
don't know if the staging patch should better go in via the greybus tree
or via pwm. Both is possible without needing coordination.

Best regards

This would've been much easier if it had been a single patch. Now I have
to either make you redo the whole series because you've misspelled PWM
or I have to go and update it myself in most of the above patches. Hint:
I'll do the latter.

There is really no reason to split this up into this many patches for
such a trivial change.
