The old_flags variable is declared twice in __dev_change_flags(), causing a shadow variable warning. This patch fixes the issue by removing the redundant declaration, reusing the existing old_flags variable instead. net/core/dev.c:9225:16: warning: declaration shadows a local variable [-Wshadow] 9225 | unsigned int old_flags = dev->flags; | ^ net/core/dev.c:9185:15: note: previous declaration is here 9185 | unsigned int old_flags = dev->flags; | ^ 1 warning generated. Remove the redundant inner declaration and reuse the existing old_flags variable since its value is not needed outside the if block, and it is safe to reuse the variable. This eliminates the warning while maintaining the same functionality.

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 reStructuredText 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.
