+Subject: [PATCH] cpupower: Correct return type of cpu_power_is_cpu_online in
+ cpufreq
+To: Thomas Renninger <trenn@suse.com>

+Cc: linux-kernel@vger.kernel.org
+
+When converting to a shared library in ac5a181d065d ("cpupower: Add
+cpuidle parts into library"), cpu_freq_cpu_exists was converted to
+cpupower_is_cpu_online. cpu_req_cpu_exists returned 0 on success and
+-ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success.
+Check for the correct return value in cpufreq-set.

+The iio tools have been updated as new event types have been added to
+the kernel. The tools currently use the standard system headers which
+means that the system may not have the newest defintitions. This leads
+to build failures when building newer tools on older hosts:
+
+gcc -Wall -g -D_GNU_SOURCE   -c -o iio_event_monitor.o
+iio_event_monitor.c

+iio_event_monitor.c:97:3: note: (near initialization for
+‘iio_modifier_names’)
+<builtin>: recipe for target 'iio_event_monitor.o' failed
+
+Switch to using the header from the kernel tree to ensure the newest
+defintions are always picked up.
