Subject: [PATCH v3 2/2] PCI: j721e: Use inline reset GPIO assignment and drop local variable
Date: Mon, 27 Oct 2025 14:33:06 +0530 [thread overview]
Message-ID: <20251027090310.38999-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20251027090310.38999-1-linux.amoon@gmail.com>
The result of devm_gpiod_get_optional() is now assigned directly
assigned to pcie->reset_gpio. This removes a superfluous local gpiod
variable, improving code readability and compactness. The functionality
remains unchanged, but the code is now more streamlined
