Subject: [PATCH 1/7] net/hns3: fix variable overflow
Date: Tue, 8 Apr 2025 16:30:54 +0800 [thread overview]
Message-ID: <20250408083100.2845040-2-huangdengdui@huawei.com> (raw)
In-Reply-To: <20250408083100.2845040-1-huangdengdui@huawei.com>
The number of interrupt vector may exceed the range of uint8_t.
So hns3_unmap_rx_interrupt() should use uint16_t for 'vec' variable.
Fixes: 02a7b55657b2 ("net/hns3: support Rx interrupt")
