cpufreq: speedstep-lib: Use int type to store negative error codes

2025-09-05T18:28:46+00:00

Change the return type of the speedstep_get_freqs() function from unsigned int to int because it may return negative error codes. For the same reason, change the 'ret' variables to int type as well. No effect on runtime. Signed-off-by: Qianfeng Rong Acked-by: Viresh Kumar Link: https://patch.msgid.link/20250902114545.651661-4-rongqianfeng@vivo.com Signed-off-by: Rafael J. Wysocki

cpufreq: speedstep: fix speedstep_detect_processor()'s return type

2018-05-10T09:46:00+00:00

speedstep_detect_processor() is declared as returing an 'enum speedstep_processor' but use an 'int' in its definition. Fix this by using 'enum speedstep_processor' in its definition too. Signed-off-by: Luc Van Oostenryck Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

2018-02-15T00:15:52+00:00

x86_mask is a confusing name which is hard to associate with the processor's stepping. Additionally, correct an indent issue in lib/cpu.c.
