[PATCH 5.15.y 1/2] gpio: pca953x: Utilise temporary variable for struct gpio_chip

[Sasha Levin <sashal@kernel.org>]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 9da0a75ea7ced4731b1f2c6c67dc409e40efb95a ]

We have a temporary variable to keep pointer to struct gpio_chip.
Utilise it where it makes sense.
