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.
