Subject: misc-utils: flashcp: Fix uninitialized variable ‘wrlast_buf’ compiling warning
X-Git-Tag: v2.3.0~6
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=555a652dfe40619fd316ff7016570734450daf44;p=mtd-utils.git

misc-utils: flashcp: Fix uninitialized variable ‘wrlast_buf’ compiling warning

The compiler compains following message:
 misc-utils/flashcp.c:439:3: warning: ‘wrlast_buf’ may be used
 uninitialized in this function
It won't bring any problems because variable '‘wrlast_buf’ is always
initialized before being used. Fix the warning by setting 'wrlast_buf'
as NULL when declaring it.
