Linus Torvalds 8654fa5ca3 pwm: Fix an off-by-one in the stm32 driver Hardware engineers tend to start counting at 1 while the software guys usually start with 0. This isn't so nice because that results in drivers where pwm device #2 needs to use the hardware registers with index 3. With the commits `796b942f65` ("mfd: stm32-timers: Add some register definitions with a parameter") `7cea05ae1d` ("pwm-stm32: Make use of parametrised register definitions") (merged for v6.11-rc1) I tried to improve the situation and make this counting mismatch more explicit and transparent. However in one instance I failed to add the needed +1. This was noticed by Fabrice Gasnier (however in a way that made me hesitate to add a "Reported-by:" tag, see https://lore.kernel.org/linux-pwm/3515a8f3-436e-4d14-9bac-dfe6aa869819@foss.st.com), thanks to him for catching the issue. A small patch fixing that mismatch is the only change included here. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmbavHoACgkQj4D7WH0S /k71QAf/YE64gkrQZ1nlYWrU0XLH49d+GDI92Q3qYgU0HLontdH+k1hoBra3SgvR OSKeyJdXM9ffQ5MDqYE+wKiriAdx87bnqlIp1eUeIcZmmSpR7x1XEKGRclpYJXPz MFEuK5cxzQAP2bihWavkcl1Ws5LmuTKJMJUbtrDW5R6jYQUesRx5Dxt/U+e8s8cu HL205kNWGpCcyuLmiUNeu3mlP0qX4EbCa9iuhMvkuz7nNjrNSZ3Mdsc0bIEzKxKc NL3yLYqPcOO7z6whGH/05SjRFtKpRrZJ1Pnn4VpEfmfoWINIGDslqPmsxeodMux3 emkXmTWpmu+ptnk9Bgzl6NAqGijFMQ== =d3K/ -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.11-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fix from Uwe Kleine-König: "Fix an off-by-one in the stm32 driver.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
