kconfig: add xstrdup() helper

2018-03-01T15:26:47+00:00

We already have xmalloc(), xcalloc(), and xrealloc((). Add xstrdup() as well to save tedious error handling. Signed-off-by: Masahiro Yamada

kconfig: make conf_unsaved a local variable of conf_read()

2018-01-21T15:49:31+00:00

conf_unsaved is initialized by conf_read_simple(), but it is possible to move it to conf_read() so that it can be a local variable. Signed-off-by: Masahiro Yamada

kconfig: drop 'boolean' keyword

2018-01-21T15:49:29+00:00

No more users of this keyword. Drop it according to the notice by commit 6341e62b212a ("kconfig: use bool instead of boolean for type definition attributes"). Signed-off-by: Masahiro Yamada Acked-by: Luis R. Rodriguez

kconfig: add unexpected data itself to warning

2016-05-10T15:20:19+00:00

If the .config parser runs into unexpected data it emits warnings like: .config:6911:warning: unexpected data Add the unexpected data itself to this warning. That makes it easier to discover what is actually going wrong: .config:6911:warning: unexpected data: CONFOG_CHARGER_TPS65217=m Signed-off-by: Paul Bolle Signed-off-by: Michal Marek

unbreak allmodconfig KCONFIG_ALLCONFIG=...

2016-02-01T14:12:40+00:00

Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections?

kconfig: Delete unnecessary checks before the function call "sym_calc_value"

2015-08-19T14:41:02+00:00

The sym_calc_value() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Michal Marek

kconfig: Remove unnecessary prototypes from headers

kconfig: use va_end to match corresponding va_start

2015-01-27T15:52:43+00:00

Although on some systems va_end is a no-op, it is good practice to use va_end, especially since the manual states: "Each invocation of va_start() must be matched by a corresponding invocation of va_end() in the same function." Signed-off-by: Colin Ian King Signed-off-by: Michal Marek

kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT

2014-04-07T23:36:09+00:00

"make allnoconfig" exists to ease testing of minimal configurations. Documentation/SubmitChecklist includes a note to test with allnoconfig. This helps catch missing dependencies on common-but-not-required functionality, which might otherwise go unnoticed. However, allnoconfig still leaves many symbols enabled, because they're hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't typically get build-tested with those disabled. To address this, introduce a new Kconfig option "allnoconfig_y", used on symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED (which then selects CONFIG_EXPERT). allnoconfig will then disable all the symbols hidden behind those. Signed-off-by: Josh Triplett Tested-by: Paul E.
