Subject: [PATCH 0/7] hwmon: zero-initialization instead of memset
Date: Sat, 30 May 2026 22:13:45 +0000	[thread overview]
Message-ID: <20260530221353.159461-1-manishbaing2789@gmail.com> (raw)

Hi all,

This patch series cleans up memory initialization across several
hardware monitoring (hwmon) drivers by replacing explicit memset() calls
with empty brace initialization (= {}).

Following similar cleanups in the IIO subsystem [1], this series updates 
these drivers to stop using memset() for stack memory initialization.
As noted in those discussions [2], using empty brace initialization (= {})
is the preferred approach. 

Beyond simple replacements, a few drivers (nct6683, nct6775-platform, it87)
were using memset() inside a for-loop. To fix this, the variable 
declarationwas moved directly inside the loop and zero-initialized there. 
This safely resets the data on every iteration and makes the code much 
cleaner.

Testing:
- Compiled all modified files using `make W=1` with no warnings or errors.
