Caused by commit fb3957af9ec6 ("pwm: Add Rust driver for T-HEAD TH1520 SoC") presumably interacting with something merged earlier in my tree. If someone could provide me with an appropriate merge resolution, I will apply it. I have used the pwm tree from next-20251024 for today. --=20 Cheers, Stephen Rothwell --Sig_/Q9AjUHu9ckDak5Qf2iLUM7h Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmj+0DQACgkQAVBC80lX 0GygJAf/bzLHVaD9z9tJmRBDc1RORE7DwIbZ2T4TgTDLgTJNJB/5fKgwTuT08lP9 ZNDIgBwVZ/LLTXfTvbmUv25FBHf9mFQ3sYbvuc8lbLClapnGb+PQR2YfTC58j116 vRbvv91TU1K3eR8As5atPqFT7BvCiWv4ElscRJAYq1imrd7AiEjBuGzRpecyTmV2 j/9yw1AeevDB3b4EXLXJD8N8nAwUr2llrxQWN6OusPKYSINXsl2blKYQgIAbp0QJ MW28Uml0buqXYHgoiZMjQ7+vbe31UwzaVOzKP1981IEAtsJjqV6I/xZCPamUtn7A IjzwosXhbGcQGavWQzM7L+KknDJuMQ== =r2db -----END PGP SIGNATURE----- --Sig_/Q9AjUHu9ckDak5Qf2iLUM7h--
