The early-exit didn't seem to matter on the AST2500, but on the AST2600 the SD clock genuinely may not be running on entry to aspeed_sdhci_set_clock(). Remove the early exit to ensure we always run sdhci_enable_clk(). Signed-off-by: Andrew Jeffery <redacted> --- drivers/mmc/host/sdhci-of-aspeed.c | 3 --- 1 file changed, 3 deletions(-)
