Subject: [PATCH v3] gpio: gpio-imx-scu: Use ARRAY_SIZE for array length
Date:   Thu, 10 Aug 2023 18:36:00 +0530

From: Rajeshwar R Shinde <coolrrsh@gmail.com>

Use of macro ARRAY_SIZE to calculate array size minimizes
the redundant code and improves code reusability.
This fixes warnings reported by Coccinelle:
drivers/gpio/gpio-imx-scu.c:106:32-33: WARNING: Use ARRAY_SIZE

v1->v2
ARRAY_SIZE calculates array length, so changed
gc->ngpio = ARRAY_SIZE(scu_rsrc_arr)/sizeof(unsigned int) to
gc->ngpio = ARRAY_SIZE(scu_rsrc_arr)

v2->v3
added linux/kernel.h containing ARRAY_SIZE definition
