Dear,
I have a problem with commit 8bc487d150b939e69830c39322df4ee486efe381
in file drivers/of/of_mdio.c in function of_phy_find_device.
As you see, this function define match() as a nested function. My
compiler (powerpc-e500-linux-gnu-gcc-3.4.1) raise an error during link
due to this nested definition:
drivers/built-in.o(.text+0x5e2a4): In function `of_phy_find_device':
/home/jezz/linux-next/drivers/of/of_mdio.c:107:
undefined reference to `__trampoline_setup'
I am sure I could solve problem by rebuilding my toolchain.
Nevertheless, I think nested function definition is not perfectly
supported by all compilers. Also, I suggest to place function match()
outside of scope of of_phy_find_device as in following patch.
