Subject: [PATCH] platform/chrome: cros_ec_lightbar: Fix response size initialization
Date: Fri, 30 Jan 2026 04:03:35 +0000 [thread overview]
Message-ID: <20260130040335.361997-1-tzungbi@kernel.org> (raw)
Commit 1e7913ff5f9f ("platform/chrome: cros_ec_lightbar: Reduce
ligthbar get version command") meant to set smaller values for both
request and response sizes.
However, it incorrectly assigned the response size to the `result` field
instead of `insize`. Fix it.

As the cut-off date for the next merge window is approaching. I really
hope to include the fix in the cycle. Sent the fix by myself. See also
