commitb3b7c4795c("x86/MCE: Serialize sysfs changes") introduced a min interval limitation when setting the check interval for polled MCEs. However, the logic is that 0 disables polling for corrected MCEs, see Documentation/x86/x86_64/machinecheck. The limitation prevents disabling. Remove this limitation and allow the value 0 to disable polling again.

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.
