Description Max Steel 2020-05-05 15:01:45 UTC 
When VIDEO_TVP5150 is selected (yes or moduled) the build will fail while REGMAP_I2C isn't selected.

Reproducible: Always

Steps to Reproduce:
1. emerge gentoo-sources-5.6.10
2. activate VIDEO_TVP5150
3. make modules_install

Actual Results:  
ERROR: "__devm_regmap_init_i2c" [drivers/media/i2c/tvp5150.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:93: __modpost] Fehler 1
make: *** [Makefile:1283: modules] Fehler 2


Expected Results:  
compiles and finishes

I found out that tvp5150 requires REGMAP_I2C,
sadly i cant provide a valid patch but after i manually added
  select REGMAP_I2C'
into
  config VIDEO_TVP5150
in drivers/media/i2c/Kconfig and run
make oldconfig
make install modules_install
it builds and install successful.

Can you attach your .config to make my life easier?

.config
Comment 4 Max Steel 2020-05-06 19:20:02 UTC 
sorry for the delay.

the attached .config produces the error.


The error just got to my attention because i just did upgrade my PC after several months without upgrades. But i dont need this Option really, i just noticed it.
Comment 5 Mike Pagano gentoo-dev 2020-05-13 16:49:40 UTC 
This fix will be in the next release of gentoo-sources (5.6.13)

    VIDEO_TVP5150 requies REGMAP_I2C to build.  Select it by default.
