hwmon: (ltc2992) Set `can_sleep` flag for GPIO chip
[ Upstream commit ab00709310eedcd8dae0df1f66d332f9bc64c99e ]
The ltc2992 drivers uses a mutex and I2C bus access in its GPIO chip `set`
and `get` implementation. This means these functions can sleep and the GPIO
chip should set the `can_sleep` property to true.
This will ensure that a warning is printed when trying to set or get the
GPIO value from a context that potentially can't sleep.
Fixes: 9ca26df1ba25 ("hwmon: (ltc2992) Add support for GPIOs.")
