Subject: [PATCH] MIPS: Always define builtin_cmdline
|
||
|
|
|
||
|
|
Commit 7784cac69735 ("MIPS: cmdline: Clean up boot_command_line
|
||
|
|
initialization") made use of builtin_cmdline conditional upon plain C if
|
||
|
|
statements rather than preprocessor #ifdef's. This caused build failures
|
||
|
|
for configurations with CONFIG_CMDLINE_BOOL=n where builtin_cmdline
|
||
|
|
wasn't defined, for example:
|
||
|
|
|
||
|
|
arch/mips/kernel/setup.c: In function 'bootcmdline_init':
|
||
|
|
>> arch/mips/kernel/setup.c:582:30: error: 'builtin_cmdline' undeclared
|
||
|
|
(first use in this function); did you mean 'builtin_driver'?
|
||
|
|
strlcpy(boot_command_line, builtin_cmdline, COMMAND_LINE_SIZE);
|
||
|
|
^~~~~~~~~~~~~~~
|
||
|
|
builtin_driver
|
||
|
|
arch/mips/kernel/setup.c:582:30: note: each undeclared identifier is
|
||
|
|
reported only once for each function it appears in
|
||
|
|
|
||
|
|
Fix this by defining builtin_cmdline as an empty string in the affected
|
||
|
|
configurations. All of the paths that use it should be optimized out
|
||
|
|
anyway so the data itself gets optimized away too.
