      i2c: core: Add new i2c_acpi_new_device helper function · 605f8fc2
      Hans de Goede 提交于
      By default the i2c subsys creates an i2c-client for the first I2cSerialBus
      resource of an acpi_device, but some acpi_devices have multiple
      I2cSerialBus resources and we may want to instantiate i2c-clients for
      the others.
      
      This commit adds a new i2c_acpi_new_device function which can be used to
      create an i2c-client for any I2cSerialBus resource of an acpi_device.
      
      Note that the other resources may even be on a different i2c bus, so just
      retrieving the client address is not enough.
      
      Here is an example DSDT excerpt from such a device:

      i2c: core: Allow getting ACPI info by index · 417f7843
      Hans de Goede 提交于
      Modify struct i2c_acpi_lookup and i2c_acpi_fill_info() to allow
      using them to get the info from a certain index in the ACPI-resource
      list rather then taking the first I2cSerialBus resource.

      mm/swap: don't BUG_ON() due to uninitialized swap slot cache · 452b94b8
      Linus Torvalds 提交于
      This BUG_ON() triggered for me once at shutdown, and I don't see a
      reason for the check.  The code correctly checks whether the swap slot
      cache is usable or not, so an uninitialized swap slot cache is not
      actually problematic afaik.
      
      I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since
      I'm not sure why that seemingly pointless check was there.  I suspect
      the real fix is to just remove it entirely, but for now we'll warn about
      it but not bring the machine down.
