2910_TVP5150-Fix-build-issue-by-selecting-REGMAP-I2C.patch has been already applied by upstream So it patches an entry above unintended by fuzzy and "config VIDEO_TVP514X" also gets an "select REGMAP_I2C" Reproducible: Always
A full log of the output would be helpful.
I am not using emerge, but a full patch output: --- Applying patch patches/genbase/2910_TVP5150-Fix-build-issue-by-selecting-REGMAP-I2C.patch patching file drivers/media/i2c/Kconfig Hunk #1 succeeded at 387 with fuzz 2 (offset 9 lines).
Explanation: I have my own linux kernel build script, but I use the Gentoo patches. I look how these patches behave, especially if a fuzzy patch arrives. So, this is no bug if gentoo-sources emerges with fuzzy turned off while patch works
Thanks for reporting. Removed from genpatches 5.7 and 5.8 for next release.
Make that next, next release. Just missed for the next round.
