kbuild test robot gets the following compilation warning using gcc 7.4
cross compilation for c6x (GCC_VERSION=7.4.0 make.cross ARCH=c6x).

drivers//scsi/sd_zbc.c: In function 'sd_zbc_read_zones':
>> include/linux/kernel.h:62:48: warning: 'zone_blocks' may be used
uninitialized in this function [-Wmaybe-uninitialized]
#define __round_mask(x, y) ((__typeof__(x))((y)-1))
^
drivers//scsi/sd_zbc.c:464:6: note: 'zone_blocks' was declared here
u32 zone_blocks;
^~~~~~~~~~~
This is a false-positive report. The variable zone_blocks is always
initialized in sd_zbc_check_zones() before use. It is not initialized
only and only if sd_zbc_check_zones() fails.
Avoid this warning by initializing the zone_blocks variable to 0.

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.
