Subject: [PATCH] thermal: int340x: Fix sysfs group leak on DLVR registration failure
Date: Mon, 15 Dec 2025 11:15:38 +0530	[thread overview]
Message-ID: <20251215054538.3483331-1-kaushlendra.kumar@intel.com> (raw)

When DLVR sysfs group creation fails in proc_thermal_rfim_add(),
the function returns immediately without cleaning up the FIVR
group that may have been created earlier.

Add proper error unwinding to remove the FIVR group before
returning failure.
