From: Prashant Malani Date: Thu, 29 Oct 2020 22:27:30 +0000 (-0700) Subject: platform/chrome: cros_ec_typec: Relocate set_port_params_v*() functions X-Git-Tag: accepted/tizen/unified/20230118.172025~8182^2~7 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0498710be002b35bcb43895c4133a4c4bbfd837e;p=platform%2Fkernel%2Flinux-rpi.git platform/chrome: cros_ec_typec: Relocate set_port_params_v*() functions Move the cros_typec_set_port_params_v0/v1() functions closer to the place where they are called, cros_typec_port_update(). While we are performing the relocation, also move cros_typec_get_mux_info() closer to its call-site. No functional changes are introduced by this commit.
