Subject: [PATCH 4.19 139/306] thermal: rcar_thermal: fix duplicate IRQ request

From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

[ Upstream commit df016bbba63743bbef9ff5c6c282561211dd72cc ]

The driver on R8A77995 requests the same IRQ twice since
platform_get_resource() is always called for the 1st IRQ resource.

Fixes: 1969d9dc2079 ("thermal: rcar_thermal: add r8a77995 support")
