[ Upstream commit b6cd7adec0cf03f0aefc55676e71dd721cbc71a8 ]
If request_irq() fails in st_rtc_probe(), there is no need to enable
the irq, and if it succeeds, disable_irq() after request_irq() still has
a time gap in which interrupts can come.
request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when
request IRQ.
Fixes: b5b2bdfc28 ("rtc: st: Add new driver for ST's LPC RTC")

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.
