Subject: [PATCH] regulator: max77857: mark more functions static
Date:   Tue, 18 Jul 2023 21:39:31 +0200

From: Arnd Bergmann <arnd@arndb.de>

A few functions in the new driver are global but only used in this file:

drivers/regulator/max77857-regulator.c:209:5: error: no previous prototype for 'max77859_get_voltage_sel' [-Werror=missing-prototypes]
drivers/regulator/max77857-regulator.c:221:5: error: no previous prototype for 'max77859_set_current_limit' [-Werror=missing-prototypes]
drivers/regulator/max77857-regulator.c:235:5: error: no previous prototype for 'max77859_get_current_limit' [-Werror=missing-prototypes]

Mark them static, which produces potentially better code and avoids the warning.
