counter: Reduce DEFINE_COUNTER_ARRAY_POLARITY() to defining counter_array
A spare warning was reported for drivers/counter/ti-ecap-capture.c::
sparse warnings: (new ones prefixed by >>)
>> drivers/counter/ti-ecap-capture.c:380:8: sparse: sparse: symbol 'ecap_cnt_pol_array' was not declared. Should it be static?
vim +/ecap_cnt_pol_array +380 drivers/counter/ti-ecap-capture.c
379
> 380 static DEFINE_COUNTER_ARRAY_POLARITY(ecap_cnt_pol_array, ecap_cnt_pol_avail, ECAP_NB_CEVT);
381
The first argument to the DEFINE_COUNTER_ARRAY_POLARITY() macro is a
token serving as the symbol name in the definition of a new
struct counter_array structure. However, this macro actually expands to
two statements::
#define DEFINE_COUNTER_ARRAY_POLARITY(_name, _enums, _length) \
DEFINE_COUNTER_AVAILABLE(_name##_available, _enums); \
struct counter_array _name = { \
.type = COUNTER_COMP_SIGNAL_POLARITY, \
.avail = &(_name##_available), \
.length = (_length), \
}
Because of this, the "static" on line 380 only applies to the first
statement. This patch splits out the DEFINE_COUNTER_AVAILABLE() line
and leaves DEFINE_COUNTER_ARRAY_POLARITY() as a simple structure
definition to avoid issues like this.
