When CONFIG_PM is disabled, we get a couple of unused functions:
drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:927:13: error: 'mtk_jpeg_clk_off' defined but not used [-Werror=unused-function]
static void mtk_jpeg_clk_off(struct mtk_jpeg_dev *jpeg)
^~~~~~~~~~~~~~~~
drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:916:13: error: 'mtk_jpeg_clk_on' defined but not used [-Werror=unused-function]
static void mtk_jpeg_clk_on(struct mtk_jpeg_dev *jpeg)
Rather than adding more error-prone #ifdefs around those, this patch
removes the existing #ifdef checks and marks the PM functions as __maybe_unused
to let gcc do the right thing.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
