We're doing some needless string copies when trying to assign the proper `prop` string. We can make `prop` a const char* and simply assign to string literals. For the case where a format string is used, let's extract the parsing logic out into sx9324_parse_phase_prop(). We no longer need to create copies or allocate new memory. sx9324_parse_phase_prop() will simply return the default def value if it fails. This also cleans up some deprecated strncpy() uses [1]. Furthermore, let's clean up this code further by removing some unused defines: | #define SX9324_PIN_DEF "semtech,ph0-pin" | #define SX9324_RESOLUTION_DEF "semtech,ph01-resolution" | #define SX9324_PROXRAW_DEF "semtech,ph01-proxraw-strength" Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://github.com/KSPP/linux/issues/90 Cc: linux-hardening@vger.kernel.org Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Stephen Boyd <swboyd@chromium.org> Link: https://lore.kernel.org/r/20240201-strncpy-drivers-iio-proximity-sx9324-c-v5-1-78dde23553bc@google.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
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.
