Per the datasheet for max6697, OVERT mask and ALERT mask are different.
For example, the 7th bit of OVERT is the local channel but for alert
mask, the 6th bit is the local channel. Therefore, we can't apply the
same mask for both registers. In addition to that, the max6697 driver
is supposed to be compatibale with different models. I manually went over
all the listed chips and made sure all chip types have the same layout.
Testing;
mask value of 0x9 should map to 0x44 for ALERT and 0x84 for OVERT.
I used iotool to read the reg value back to verify. I only tested this
change on max6581.

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.
