extcon: cht-wc: Return from default case to avoid warnings

2018-08-28T02:21:15Z

When we have first case to fall through it's not enough to put single comment there to satisfy compiler. Instead of doing that, return fall back value directly from default case. This to avoid following warnings: drivers/extcon/extcon-intel-cht-wc.c: In function ‘cht_wc_extcon_get_charger’: include/linux/device.h:1420:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/extcon/extcon-intel-cht-wc.c:148:3: note: in expansion of macro ‘dev_warn’ dev_warn(ext->dev, ^~~~~~~~ drivers/extcon/extcon-intel-cht-wc.c:152:2: note: here case CHT_WC_USBSRC_TYPE_SDP: ^~~~ Signed-off-by: Andy Shevchenko Signed-off-by: Chanwoo Choi

extcon: Make static analyzer happy about union assignment

2018-08-28T02:21:14Z

When assign unions we need to supply non-scalar value, otherwise static analyzer is not happy: CHECK drivers/extcon/extcon.c drivers/extcon/extcon.c:631:22: warning: cast to non-scalar Signed-off-by: Andy Shevchenko Signed-off-by: Chanwoo Choi

Chanwoo writes: Update extcon for 4.19 Detailed description for this pull request: 1. Release locking when sending the connector state in extcon_sync() - Previously, extcon used the spinlock before calling the notifier_call_chain to prevent the scheduled out of task and to prevent the notification delay. When spinlock is locked for sending the notification, deadlock issue occured on the side of extcon consumer device. To fix this issue on extcon consumer device, release locking when sending the connector state. 2. Fix minor issues of extcon provider driver - extcon-intel-int3496.c uses 'linux/gpio/consumer.h' instead of 'linux/gpio.h' - extcon-usbc-cors-ec.c adds SPDX license and fix the wrong license information

extcon: Release locking when sending the notification of connector state

2018-07-12T00:06:31Z

Previously, extcon used the spinlock before calling the notifier_call_chain to prevent the scheduled out of task and to prevent the notification delay. When spinlock is locked for sending the notification, deadlock issue occured on the side of extcon consumer device. To fix this issue, extcon consumer device should always use the work. it is always not reasonable to use work. To fix this issue on extcon consumer device, release locking when sending the notification of connector state.
