Use _get_optional as some platforms might not provide the px and cx regulators. This avoids printing the following for each unavailable regulator: [ 4.350229] qcom_q6v5_pas 5c00000.remoteproc: supply cx not found, using dummy regulator [ 4.374224] qcom_q6v5_pas 5c00000.remoteproc: supply px not found, using dummy regulator Signed-off-by: Abel Vesa <abel.vesa@linaro.org> Acked-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Link: https://lore.kernel.org/r/20220713152835.3848875-1-abel.vesa@linaro.org
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.
