Subject: [PATCH 1/4] firmware: qcom: scm: remove unused arguments from SHM
 bridge routines

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

qcom_scm_shm_bridge_create() and qcom_scm_shm_bridge_delete() take
struct device as argument but don't use it. Remove it from these
functions' prototypes.
