PM / devfreq: exynos-bus: Fix NULL pointer dereference
Fix exynos-bus NULL pointer dereference by correctly using the local generated freq_table to output the debug values instead of using the profile freq_table that is not used in the driver. Reported-by: Marek Szyprowski <m.szyprowski@samsung.com> Tested-by: Marek Szyprowski <m.szyprowski@samsung.com> Fixes: b5d281f6c16d ("PM / devfreq: Rework freq_table to be local to devfreq struct") Cc: stable@vger.kernel.org Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
