Subject: [PATCH 04/35] ethtool: Fix compilation warning when pretty dump is
|
|
|
disabled

When pretty dump is disabled (i.e., configure --disable-pretty-dump),
|
|
|
gcc 11.2.1 emits the following warning:
|
|
|
|
|
|
ethtool.c: In function ‘dump_regs’:
|
|
|
ethtool.c:1160:31: warning: comparison is always false due to limited range of data type [-Wtype-limits]
|
|
|
1160 | for (i = 0; i < ARRAY_SIZE(driver_list); i++)
|
|
|
| ^
|
|
|
|
|
|
Fix it by avoiding iterating over 'driver_list' when pretty dump is
|
|
|
disabled.
