Subject: [PATCH 1/7] soc: aspeed: lpc-snoop: Cleanup resources in stack-order
Date: Fri, 11 Apr 2025 10:38:31 +0930 [thread overview]
Message-ID: <20250411-aspeed-lpc-snoop-fixes-v1-1-64f522e3ad6f@codeconstruct.com.au> (raw)
In-Reply-To: <20250411-aspeed-lpc-snoop-fixes-v1-0-64f522e3ad6f@codeconstruct.com.au>
Free the kfifo after unregistering the miscdev in
aspeed_lpc_disable_snoop() as the kfifo is initialised before the
miscdev in aspeed_lpc_enable_snoop().
Fixes: 3772e5da4454 ("drivers/misc: Aspeed LPC snoop output using misc chardev")
