Subject: [PATCH] media: dvb-frontends: drx39xyj: remove obsolete sign extend macros
Date: Wed, 3 May 2017 15:43:09 +0200 [thread overview]
Message-ID: <1493818989-18810-1-git-send-email-martink@posteo.de> (raw)
DRX_S9TOS16 and DRX_S24TODRXFREQ are simply not used. Furthermore,
sign_extend32() should be used for sign extension. (Also, the comment
describing DRX_S24TODRXFREQ was wrong). So remove these macros.
