Checkpatch emits WARNING: Too many leading tabs - consider code
refactoring. One level of indentation may be removed by inverting an
if statement conditional (and returning if new conditional evaluates
to true). Code contains switch statement that also contains multiple
layers of indentation. Indentation may be reduced by breaking out of
the case statement in multiple places instead of guarding code with
if/else statements.
Invert conditional. Return original error code if new conditional
evaluates to true. Break out of case blocks instead of using
if/else. Do not modify program logic.

'auth_type - 1' is used as an index into a key table. Adding a variable
appropriately named simplifies the code and adds meaning when
reading. Adding a pointer variable of type struct *kpa_key_t adds to
readability by removing the table access each time the key is used.
The key index is used to create a string so having it named adds
additional meaning when creating the string.
Declare variable 'key_index' and define it at declaration time. Declare
a pointer variable 'key' and define it to point to the correct key in
the key table.
