Subject: clk dereference in arch/sh/kernel/cpufreq.c
Date: Thu, 3 Jan 2013 10:40:20 +0100 (CET)	[thread overview]
Message-ID: <alpine.DEB.2.02.1301031038030.1989@hadrien> (raw)

There has been a discussion recently about how the result of get_clk
should be an opaque handle, not a value that can be dereferenced:

https://lkml.org/lkml/2012/12/20/105

There is such a dereference in arch/sh/kernel/cpufreq.c, in the function
sh_cpufreq_cpu_init:

freq_table = cpuclk->nr_freqs ? cpuclk->freq_table : NULL;

It was not obvious to me, however, what API function should be used
instead, so I am just reporting the (potential) problem.

thanks,
julia
