From: Zhen Lei thunder.leizhen@huawei.com
[ Upstream commit 6fd8f323b3e4e5290d02174559308669507c00dd ]
When the call to platform_get_irq() to obtain the IRQ of the lcd fails, the returned error code should be propagated. However, we currently do not explicitly assign this error code to 'ret'. As a result, 0 was incorrectly returned.
