Remove strtobool()

[PATCH 11/30] greybus: svc: Use kstrtobool() instead of strtobool()

Posted by Christophe JAILLET 3 years, 5 months ago

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)

This patch is part of a serie that axes all usages of strtobool().
Each patch can be applied independently from the other ones.

The last patch of the serie removes the definition of strtobool().

You may not be in copy of the cover letter. So, if needed, it is available
at [1].

Sure, why not:
