    net: ipa: introduce ipa_reg() · 6a244b75
    Alex Elder authored
    Create a new function that returns a register descriptor given its
    ID.  Change ipa_reg_offset() and ipa_reg_n_offset() so they take a
    register descriptor argument rather than an IPA pointer and register
    ID.  Have them accept null pointers (and return an invalid 0 offset),
    to avoid the need for excessive error checking.  (A warning is issued
    whenever ipa_reg() returns 0).
    
    Call ipa_reg() or ipa_reg_n() to look up information about the
    register before calls to ipa_reg_offset() and ipa_reg_n_offset().
    Delay looking up offsets until they're needed to read or write
    registers.
