drm: sun4i: fix probe error handling
gcc points out a possible uninitialized variable use in sun4i_dclk_create(): drivers/gpu/drm/sun4i/sun4i_dotclock.c: In function 'sun4i_dclk_create': drivers/gpu/drm/sun4i/sun4i_dotclock.c:139:12: error: 'clk_name' may be used uninitialized in this function [-Werror=maybe-uninitialized] init.name = clk_name; The warning only shows up when CONFIG_OF is disabled, and the property is never filled, but the same bug can show up even when CONFIG_OF is enabled but of_property_read_string_index returns another error. To fix it, this ensures that sun4i_dclk_create propagates any error from of_property_read_string_index.
