Ouch. Sorry, I should have spotted this during review.
Jiri, could you apply the following simple fix:
From 3c3bff3c6d36b3a9b2aac5993da1345f3b12e6ac Mon Sep 17 00:00:00 2001
From: Benjamin Tissoires <redacted>
Date: Sat, 10 Dec 2016 21:58:55 +0100
Subject: [PATCH] HID: fix missing irq field
commit ba18a9314a94 ("Revert "HID: i2c-hid: Add support for ACPI GPIO
interrupts"") removed the need for storing the irq in struct i2c_hid.
But then commit de3c99488609 ("HID: i2c-hid: Disable IRQ before freeing
buffers") forgot to update the location of the irq.
Fix this by using the actual I2C client irq.
