Linux kernel source tree
6d609b35c8
When the RTC lock and unlock functions were introduced it was likely assumed that they would always be called from irq enabled context, hence the use of local_irq_disable/enable. This is no longer true as the RTC+DDR path makes a late call during the suspend path after irqs have been disabled to enable the RTC hwmod which calls both unlock and lock, leading to IRQs being reenabled through the local_irq_enable call in omap_hwmod_rtc_lock call. To avoid this change the local_irq_disable/enable to local_irq_save/restore to ensure that from whatever context this is called the proper IRQ configuration is maintained.

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.
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.
