Subject: [PATCH] PCI: rcar: Add missing COMMON_CLK dependency
Date: Tue,  7 Sep 2021 16:45:12 +0200	[thread overview]
Message-ID: <20210907144512.5238-1-marek.vasut@gmail.com> (raw)

From: Marek Vasut <marek.vasut+renesas@gmail.com>

Add COMMON_CLK dependency, otherwise the following build error occurs:
  arm-linux-gnueabi-ld: drivers/pci/controller/pcie-rcar-host.o: in function `rcar_pcie_aarch32_abort_handler':
  pcie-rcar-host.c:(.text+0xdd0): undefined reference to `__clk_is_enabled'
This should be OK, since all platforms shipping this controller also
need COMMON_CLK enabled for their clock driver.

Fixes: a115b1bd3af0 ("PCI: rcar: Add L1 link state fix into data abort hook")

+CC Stephen, please double-check whether this is the right approach or
    whether there is some better option
