From: Christian Lamparter Date: Sun, 19 Aug 2012 19:16:54 +0000 (+0200) Subject: carl9170: remove eeprom_fix utility X-Git-Tag: 1.9.7~28 X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=1c697128c34c65740c067cefbf80a550a47ce05c;p=carl9170fw.git carl9170: remove eeprom_fix utility The carl9170 driver in the kernel doesn't have the capability anymore. Hence, this tool is no longer needed.
