Subject: staging: dgap: Fixed sparse error: same symbol redeclared with different type
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fd54889b65cc32fc64e5a6c456fbf6aab4bd258a;p=deliverable%2Flinux.git

staging: dgap: Fixed sparse error: same symbol redeclared with different type

sparse reported dgap_do_fep_load is redeclared with different type. while
fixing, I noticed __user attribute is used incorrectly in declaration.
There is no need to define __user for firware->data.

Replaced the __user with 'const uchar *' from function dgap_do_fep_load and
did the same for function dgap_do_bios_load

patch generated against: next-20140318
