Three of the newly added functions are accidently not marked 'static' which
causes a warning when building with W=1
drivers/platform/x86/thinkpad_acpi.c:10081:5: warning: no previous prototype for function 'dytc_profile_get' [-Wmissing-prototypes]
drivers/platform/x86/thinkpad_acpi.c:10095:5: warning: no previous prototype for function 'dytc_cql_command' [-Wmissing-prototypes]
drivers/platform/x86/thinkpad_acpi.c:10133:5: warning: no previous prototype for function 'dytc_profile_set' [-Wmissing-prototypes]
The functions are also present in two files, causing a link error when
both are built into the kernel:
ld.lld: error: duplicate symbol: dytc_cql_command
>>> defined at ideapad-laptop.c
>>> platform/x86/ideapad-laptop.o:(dytc_cql_command) in archive drivers/built-in.a
>>> defined at thinkpad_acpi.c
>>> platform/x86/thinkpad_acpi.o:(.text+0x20) in archive drivers/built-in.a
ld.lld: error: duplicate symbol: dytc_profile_get
>>> defined at ideapad-laptop.c
>>> platform/x86/ideapad-laptop.o:(dytc_profile_get) in archive drivers/built-in.a
>>> defined at thinkpad_acpi.c
>>> platform/x86/thinkpad_acpi.o:(.text+0x0) in archive drivers/built-in.a
ld.lld: error: duplicate symbol: dytc_profile_set
>>> defined at ideapad-laptop.c
>>> platform/x86/ideapad-laptop.o:(dytc_profile_set) in archive drivers/built-in.a
>>> defined at thinkpad_acpi.c
>>> platform/x86/thinkpad_acpi.o:(.text+0x220) in archive drivers/built-in.a
Mark these all as static to avoid both problems.
Fixes: eabe533904cb ("platform/x86: ideapad-laptop: DYTC Platform profile support")
Fixes: c3bfcd4c6762 ("platform/x86: thinkpad_acpi: Add platform profile support")
