From fbf476ea29cc7294586dcf0b89f22593458deb0d Mon Sep 17 00:00:00 2001 From: Geordan Neukum Date: Wed, 5 Jun 2019 01:09:12 +0000 Subject: staging: kpc2000: kpc_spi: remove unnecessary ulong repr of i/o addr The kpc_spi driver stashes off an unsigned long representation of the i/o mapping returned by devm_ioremap_nocache(). This is unnecessary, as the only use of the unsigned long repr is to eventually be re-cast to an (u64 __iomem *). Instead of casting the (void __iomem *) to an (unsigned long) then a (u64 __iomem *), just remove this intermediate step. As this intermediary is no longer used, also remove it from its structure.
