Subject: sh: intc: Fix up build failure introduced by radix tree changes.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6318af900ca7cb2c94b27d3c358762e6ac187e25;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sh: intc: Fix up build failure introduced by radix tree changes.

The radix tree retry logic got a bit of an overhaul and subsequently
broke the virtual IRQ subgroup build. Simply switch over to
radix_tree_deref_retry() as per the filemap changes, which the virq
lookup logic was modelled after in the first place.
