The latest changes to the rockchip clk implementation cause
tons of warnings and/or errors (depending on the configuration):
WARNING: vmlinux.o(.data+0x125394): Section mismatch in reference from the variable __compound_literal.125 to the (unknown reference) .init.rodata:(unknown)
The reason is a compount literal in a macro that refers to an
object in the .init.rodata section:
#define COMPOSITE_FRACMUX(_id, cname, pname, f, mo, df, go, gs, gf, ch) \
{ \
...
.child = &(struct rockchip_clk_branch)ch, \
}
'ch' here is placed in .data, and I could find no way to override that
using an attribute or pragma because there is no identifier associated
with it.
This patch avoids the warning by placing the names in .rodata rather than
.init.rodata. However, it is not an ideal solution because we really
want all those data structures to be discarded along with the initdata.
