A bisect landed on 0e4dcffd331fa7d ("drm/panel: raspberrypi-touchscreen: Convert to i2c's .probe_new()") which is obviously not credible. I suspect that what's happening here is that the fix you applied is making an issue somewhere else visible in defconfig and is as a result confusing the bisect. Ard mentioned an issue with non-EFI biits introduced by EFI changes here: https://lore.kernel.org/linux-arm-kernel/CAMj1kXGFa=Zriyp_mS7bbQr0wiwikt0ObjOKUSNGpJtFvLmnkg@mail.gmail.com/ which seems like a plausible culprit, bisect log: git bisect start # bad: [c9e9cdd8bdcc3e1ea330d49ea587ec71884dd0f5] Add linux-next specific files for 20230111 git bisect bad c9e9cdd8bdcc3e1ea330d49ea587ec71884dd0f5 # good: [7dd4b804e08041ff56c88bdd8da742d14b17ed25] Merge tag 'nfsd-6.2-3' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux git bisect good 7dd4b804e08041ff56c88bdd8da742d14b17ed25 # good: [ecf8827ab7dd5731813f90146d9936165b170f32] Merge branch 'drm-next' of git://git.freedesktop.org/git/drm/drm.git git bisect good ecf8827ab7dd5731813f90146d9936165b170f32 # bad: [64208e4940ede76709f1ff5b01d1b78efc2951cf] Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git git bisect bad 64208e4940ede76709f1ff5b01d1b78efc2951cf # bad: [1077dd31ba60b39a231560beec24b97eadf8bd8f] Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git git bisect bad 1077dd31ba60b39a231560beec24b97eadf8bd8f # bad: [1577a2c2aad943fbc6a5e959ae83c4ef8bc3d4de] Merge branch 'drm-next' of https://gitlab.freedesktop.org/agd5f/linux git bisect bad 1577a2c2aad943fbc6a5e959ae83c4ef8bc3d4de # good: [ec787deb2ddffc6cd6afe0e2fbbbd490ddc383ed] drm/amd: Use `amdgpu_ucode_*` helpers for GFX9 git bisect good ec787deb2ddffc6cd6afe0e2fbbbd490ddc383ed # bad: [0e4dcffd331fa7d2a6ae628b51a7f418dfa90367] drm/panel: raspberrypi-touchscreen: Convert to i2c's .probe_new() git bisect bad 0e4dcffd331fa7d2a6ae628b51a7f418dfa90367 # good: [c702545e19ebb6113d607f2a30ba2ee6cf881a3a] drm/gud: use new debugfs device-centered functions git bisect good c702545e19ebb6113d607f2a30ba2ee6cf881a3a # good: [977374cf481d3bea916b2775e6ecc682b9689550] drm/vc4: plane: Add 3:3:2 and 4:4:4:4 RGB/RGBX/RGBA formats git bisect good 977374cf481d3bea916b2775e6ecc682b9689550 # good: [67d0a30128c9f644595dfe67ac0fb941a716a6c9] drm/meson: dw-hdmi: Fix devm_regulator_*get_enable*() conversion git bisect good 67d0a30128c9f644595dfe67ac0fb941a716a6c9 # good: [29ef7605e2fd44038a70df0f46b7821464081b22] drm/i2c/sil164: Convert to i2c's .probe_new() git bisect good 29ef7605e2fd44038a70df0f46b7821464081b22 # good: [307259952625798fbea89b04aebbc5106ff18c68] drm/i2c/tda998x: Convert to i2c's .probe_new() git bisect good 307259952625798fbea89b04aebbc5106ff18c68 # good: [446757576a646eba6fae085396bdfbd74245ff28] drm/panel: olimex-lcd-olinuxino: Convert to i2c's .probe_new() git bisect good 446757576a646eba6fae085396bdfbd74245ff28 # first bad commit: [0e4dcffd331fa7d2a6ae628b51a7f418dfa90367] drm/panel: raspberrypi-touchscreen: Convert to i2c's .probe_new() --NyJhWMMx1H0jFDH9 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmO+zW4ACgkQJNaLcl1U h9AHxwf7BIatpjLOKRRwSZ6vH/lCXj5Af5JfwhejQkMbMaJQjABJCa1CkiRZ3sPX J3gj8vQg98ni2fWKtuCgQMH+9Zz342rciBN0A82EON8QDeRAlyDgnrapkvDxxEvD yEHbC+Uc7jer377/QGxkzbYYuoY6H74OAFjnM7wYwuy3o8e/SKZgUgxk/H9+VWzP f/VBTWJNmU9gFRoh/SnHgDu90V4Aa6HzkNQyaDvlK33fMpHO+4tuRKDPHWg2vQyJ h5CthYdC5GnTAvwh6Kjhasv7GBuqSp0Cc9Xv4DPGb8sYv6meszd2gCMb6hczoxsJ XNR+frbS/QAt7PFbucr+amCmHxgodA== =l6iC -----END PGP SIGNATURE----- --NyJhWMMx1H0jFDH9-- --===============6791240116257212823== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic --===============6791240116257212823==--
