PATCH v2 1/1 gpio: gpio-imx-scu: Use ARRAY_SIZE for array length

From: Rajeshwar R Shinde <[email protected]>

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

Signed-off-by Rajeshwar R Shinde <[email protected]>

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)

And you need to include kernel.h for this.
