I think this check was originally intended to go under "if (host)" above and not here. Notice the indentation mismatch/missing braces for "if (mmc)". My bad. Additionally, host->clk == NULL is not necessarily the result of clk_get() but it can also be NULL if the irq could not be assigned. Leading to unbalanced clk calls in this case. - Simon

A NULL is a valid clk cookie, so we should not be tested with IS_ERR_NULL(). Replace it with IS_ERR(). Signed-off-by: Andrew Lunn <andrew@lunn.ch> --- drivers/mmc/host/mvsdio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
