Subject: [PATCH 00/10] pwm: Constistenly name pwm_chip variables "chip"
Date: Fri, 14 Jul 2023 22:56:13 +0200	[thread overview]
Message-ID: <20230714205623.2496590-1-u.kleine-koenig@pengutronix.de> (raw)

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I marked these two as "superseded" in patchwork already.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
Uwe
