      mfd: atmel-smc: Add missing colon(s) for 'conf' arguments · 1574360a
      Lee Jones authored
      Kerneldoc valication gets confused if syntax isn't "@.*: ".
      
      Adding the missing colons squashes the following W=1 warnings:

      This is due to mixed types being compared in a min() comparison.  Fix
      this by treating values as signed and casting them to the same type
      as the receiving variable.

      Since the second min() argument can be less than 0 a signed
      variable is required for assignment.  However, the non-sized
      type size_t is passed in from the userspace handlers.  In order
      to firstly compare, then assign the smallest value, we firstly
      need to cast them both to the same as the receiving size_t typed
      variable.

      It appears as though the driver data property 'resource_size_t *base'
      was being used to store 2 different types of addresses (physical and
      IO-mapped) under a single declared type.
      
      Fortunately, no value is recalled from the driver data entry, so it
      can be easily omitted.  Instead we can use the value obtained directly
      from the platform resource to pass through  Regmap into the call-backs
      to be used for the SMCC call and use a local dedicated __iomem
      variable for IO-remapping.

      Pull SafeSetID update from Micah Morton:
       "Add additional LSM hooks for SafeSetID
      
        SafeSetID is capable of making allow/deny decisions for set*uid calls
        on a system, and we want to add similar functionality for set*gid
        calls.
      
        The work to do that is not yet complete, so probably won't make it in
        for v5.8, but we are looking to get this simple patch in for v5.8
        since we have it ready.
      
        We are planning on the rest of the work for extending the SafeSetID
