From eb0469894ba788ffdc81097b7dea822432e479d9 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 1 Nov 2021 11:27:34 +0100 Subject: [PATCH] iio: mma8452: Use correct type for return variable in IRQ handler The IRQ handler's return type is irqreturn_t. The mma8452 uses a variable to store the return value, but the variable is of type int. Change this to irqreturn_t. This makes it easier to verify that the code is correct.
