+Subject: [PATCH] uio-module-drv: Replace ioremap_nocache with ioremap
+
+The ioremap_nocache is the same as the regular ioremap and its
+definition has been dropped from the Linux kernel v5.6 onwards in
+commit 4bdc0d676a64 ("remove ioremap_nocache and devm_ioremap_nocache")
+[1]. The uio-module-drv module fails to build against these newer
+kernels, so fix it by simply replacing ioremap_nocache with ioremap.
