clk: Move clk_{save,restore}_context() to COMMON_CLK section

Browse source

[ Upstream commit f47c1b77d0 ]

The clk_save_context() and clk_restore_context() helpers are only
implemented by the Common Clock Framework.  They are not available when
using legacy clock frameworks.  Dummy implementations are provided, but
only if no clock support is available at all.

Hence when CONFIG_HAVE_CLK=y, but CONFIG_COMMON_CLK is not enabled:

    m68k-linux-gnu-ld: drivers/net/phy/air_en8811h.o: in function `en8811h_resume':
    air_en8811h.c:(.text+0x83e): undefined reference to `clk_restore_context'
    m68k-linux-gnu-ld: drivers/net/phy/air_en8811h.o: in function `en8811h_suspend':
    air_en8811h.c:(.text+0x856): undefined reference to `clk_save_context'

Fix this by moving forward declarations and dummy implementions from the
HAVE_CLK to the COMMON_CLK section.
