Subject: [PULL 40/41] hw/nvram/eeprom_at24c: Remove memset after g_malloc0
Date: Wed,  5 Mar 2025 02:21:55 +0100	[thread overview]
Message-ID: <20250305012157.96463-41-philmd@linaro.org> (raw)
In-Reply-To: <20250305012157.96463-1-philmd@linaro.org>

From: BALATON Zoltan <balaton@eik.bme.hu>

Calling memset to zero memory is not needed after g_malloc0 which
already clears memory. These used to be in separate functions but
after some patches the memset ended up after g_malloc0 and thus can be
dropped.

Fixes: 4f2c6448c3 (hw/nvram/eeprom_at24c: Make reset behavior more like hardware)
