[PATCH 1/2] drivers: sfi: Include appropriate headers in sfi_acpi.c

[PATCH 1/2] drivers: sfi: Include appropriate headers in sfi_acpi.c

[Rashika Kheria]

Include header file include/linux/sfi_acpi.h in sfi_acpi.c because
function sfi_acpi_table_parse() has its prototype declaration in
include/linux/sfi_acpi.h. Also, include include/linux/acpi.h because it
contains declarations necessary for include/linux/sfi_acpi.h.

This eliminates the following warning in sfi_acpi.c:
drivers/sfi/sfi_acpi.c:154:5: warning: no previous prototype for ‘sfi_acpi_table_parse’ [-Wmissing-prototypes]

[PATCH 2/2] drivers: sfi: Mark functions as static in sfi_core.c

[Rashika Kheria]

Mark functions sfi_map_table() and sfi_unmap_table() as static in
sfi_core.c because they are not used outside this file.

This eliminates following warning in sfi_core.c:
drivers/sfi/sfi_core.c:164:26: warning: no previous prototype for ‘sfi_map_table’ [-Wmissing-prototypes]
drivers/sfi/sfi_core.c:192:6: warning: no previous prototype for ‘sfi_unmap_table’ [-Wmissing-prototypes]
