Two drivers already implement custom debugfs handling for their i2c_adapter and more will come. So, let the core create a debugfs directory per adapter and pass that to drivers for their debugfs files. Convert the two existing users as well. Tested on a Renesas Lager board with the i2c-gpio driver. npcm7xx was tested using QEMU with the quanta-gsj target. Changes since v1: * rebased to something close to 6.7-rc1 which includes i2c/for-mergewindow * tested npcm7xx with QEMU Wolfram Sang (3): i2c: create debugfs entry per adapter i2c: gpio: move to per-adapter debugfs directory i2c: npcm7xx: move to per-adapter debugfs directory drivers/i2c/busses/i2c-gpio.c | 34 ++++------------------ drivers/i2c/busses/i2c-npcm7xx.c | 49 +++++--------------------------- drivers/i2c/i2c-core-base.c | 11 +++++++ include/linux/i2c.h | 2 ++ 4 files changed, 26 insertions(+), 70 deletions(-) -- 2.35.1
