From 11ca9624cca8134457204466d7fa6b8a99132623 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Mon, 9 Aug 2021 10:30:47 +0200 Subject: [PATCH] net/af_iucv: clean up a try_then_request_module() [ Upstream commit 4eb9eda6ba64114d98827e2870e024d5ab7cd35b ] Use IS_ENABLED(CONFIG_IUCV) to determine whether the iucv_if symbol is available, and let depmod deal with the module dependency. This was introduced back with commit 6fcd61f7bf5d ("af_iucv: use loadable iucv interface"). And to avoid sprinkling IS_ENABLED() over all the code, we're keeping the indirection through pr_iucv->...(). Signed-off-by: Julian Wiedmann Signed-off-by: Karsten Graul Signed-off-by: David S.
