The flag reporting whether an event is 'direct' or 'configurable' is available in the read-only registers EVENT_TRG. Drop this redundant information from the struct stm32_desc_irq and use the proper bit from EVENT_TRG register. On armv7a this patch reduces by 3% the size of the driver, from text data bss dec hex filename 7233 424 4 7661 1ded irq-stm32-exti.o to 6977 424 4 7405 1ced irq-stm32-exti.o Signed-off-by: Antonio Borneo <antonio.borneo@foss.st.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20220606162757.415354-6-antonio.borneo@foss.st.com
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.
