Subject: [PATCH net-next 03/13] net: ena: change sizeof() argument to be the type pointer
Date: Sun, 18 Jun 2017 14:28:08 +0300	[thread overview]
Message-ID: <1497785298-13468-4-git-send-email-netanel@amazon.com> (raw)
In-Reply-To: <1497785298-13468-1-git-send-email-netanel@amazon.com>

From: Netanel Belgazal <netanel@amazon.com>

Instead of using:
memset(ptr, 0x0, sizeof(struct ...))
use:
memset(ptr, 0x0, sizeor(*ptr))
