From abcc445acdbeb561e881fcbd8e1dc4684628cc9b Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Sun, 29 Jan 2023 01:28:44 +0800 Subject: [PATCH] riscv: move riscv_noncoherent_supported() out of ZICBOM probe It's a bit weird to call riscv_noncoherent_supported() each time when insmoding a module. Move the calling out of feature patch func.
