Subject: [PATCH] power: supply: sysfs: Remove duplicate NUL termination
|
|
|
|
GCC 15's new -Wunterminated-string-initialization notices that one of
|
|
the sysfs attr strings would lack the implicit trailing NUL byte during
|
|
initialization:
|
|
|
|
drivers/power/supply/power_supply_sysfs.c:183:57: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (32 chars into 31 available) [-Wunterminated-string-initialization]
|
|
183 | POWER_SUPPLY_ATTR(CHARGE_CONTROL_START_THRESHOLD),
|
|
| ^
|
|
drivers/power/supply/power_supply_sysfs.c:36:23: note: in definition of macro '_POWER_SUPPLY_ATTR'
|
|
36 | .attr_name = #_name "\0", \
|
|
| ^~~~~
|
|
drivers/power/supply/power_supply_sysfs.c:183:9: note: in expansion of macro 'POWER_SUPPLY_ATTR'
|
|
183 | POWER_SUPPLY_ATTR(CHARGE_CONTROL_START_THRESHOLD),
|
|
| ^~~~~~~~~~~~~~~~~
|
|
|
|
However, the macro used was explicitly adding a trailing NUL byte (which
|
|
is not needed). Remove this to avoid the GCC warning. No binary
|
|
differences are seen after this change (there was always run for a NUL
|
|
byte, it's just that the _second_ NUL byte was getting truncated).
