Subject: [PATCH 0/2] hwmon: chipcap2: fix uninitialized symbols

Two static checker warnings have been found with Smatch[1] when checking
the chipcap2 driver. Two variables might be used uninitialized under
certain circumstances (explained in the commit messages).

This series fixes the two warnings and optimizes the error paths involved.

The fixes have been tested with Smatch (including cross function database),
and the bugs could not be reproduced anymore.
