Subject: serial: max3100: Fix bitwise types
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e60955dbecb97f080848a57524827e2db29c70fd;p=linux.git

serial: max3100: Fix bitwise types

Sparse is not happy about misuse of bitwise types:

  .../max3100.c:194:13: warning: incorrect type in assignment (different base types)
  .../max3100.c:194:13:    expected unsigned short [addressable] [usertype] etx
  .../max3100.c:194:13:    got restricted __be16 [usertype]
  .../max3100.c:202:15: warning: cast to restricted __be16

Fix this by choosing proper types for the respective variables.

Fixes: 7831d56b0a35 ("tty: MAX3100")
