Subject: [PATCH 4.14 055/109] leds: pm8058: Silence pointer to integer size warning

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bjorn Andersson <bjorn.andersson@...aro.org>


[ Upstream commit 8f52df50d9366f770a894d14ef724e5e04574e98 ]

The pointer returned by of_device_get_match_data() doesn't have the same
size as u32 on 64-bit architectures, causing a compile warning when
compile-testing the driver on such platform.

Cast the return value of of_device_get_match_data() to unsigned long and
then to u32 to silence this warning.
