Just forward to linux kernel mailing list.
Thanks.
-------- Forwarded Message -------- Subject: [PATCH] c6x: kernel: setup: Type cast 'fdt' to "void *" for early_init_dt_scan() in machine_init() Date: Sun, 01 Mar 2015 16:31:29 +0800 From: Chen Gang <762976180@qq.com> To: msalter@redhat.com, a-jacquiot@ti.com CC: linux-c6x-dev@linux-c6x.org, linux-kernel@vger.kernel.org <linux-kernel@vger.kernel.org>
early_init_dt_scan() accepts "void *", so c6x needs to type cast 'fdt' to "void *" to avoid warning:
CC arch/c6x/kernel/setup.o arch/c6x/kernel/setup.c: In function 'machine_init': arch/c6x/kernel/setup.c:290:21: warning: passing argument 1 of 'early_init_dt_scan' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] early_init_dt_scan(fdt); ^ In file included from arch/c6x/kernel/setup.c:19:0: include/linux/of_fdt.h:75:13: note: expected 'void *' but argument is of type 'const void *' extern bool early_init_dt_scan(void *params); ^
