When building with -Wsometimes-uninitialized, Clang warns: drivers/iio/common/ssp_sensors/ssp_iio.c:95:6: warning: variable 'calculated_time' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] While it isn't wrong, this will never be a problem because iio_push_to_buffers_with_timestamp only uses calculated_time on the same condition that it is assigned (when scan_timestamp is not zero). While iio_push_to_buffers_with_timestamp is marked as inline, Clang does inlining in the optimization stage, which happens after the semantic analysis phase (plus inline is merely a hint to the compiler). Fix this by just zero initializing calculated_time.

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.
