The I2C driver fails to probe if CONFIG_PM_SLEEP=n because runtime PM doesn't depend on the PM sleep and in this case the runtime PM ops are not included in the driver, resulting in I2C clock not being enabled. It's much cleaner to simply allow compiler to remove the dead code instead of messing with the #ifdefs. This patch fixes such errors when CONFIG_PM_SLEEP=n: tegra-i2c 7000c400.i2c: timeout waiting for fifo flush tegra-i2c 7000c400.i2c: Failed to initialize i2c controller Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Acked-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
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 Restructured Text 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.
