Subject: drivers/staging: use current->state helpers
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2be90fef97ada3df61736435dc9ef6c3e432a747;p=openwrt%2Fstaging%2Fblogic.git

drivers/staging: use current->state helpers

Call __set_current_state() instead of assigning the new state directly.
These interfaces also aid CONFIG_DEBUG_ATOMIC_SLEEP environments,
keeping track of who changed the state.
