[PATCH AUTOSEL 6.4 14/17] fbdev: goldfishfb: Do not check 0 for platform_get_irq()

[Sasha Levin <sashal@kernel.org>]

From: Zhu Wang <wangzhu9@huawei.com>

[ Upstream commit 0650d5098f8b6b232cd5ea0e15437fc38f7d63ba ]

Since platform_get_irq() never returned zero, so it need not to check
whether it returned zero, and we use the return error code of
platform_get_irq() to replace the current return error code.

Please refer to the commit a85a6c86c25b ("driver core: platform: Clarify
that IRQ 0 is invalid") to get that platform_get_irq() never returned
zero.
