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. Signed-off-by: Tobin C.
