[PATCH 1/1] checkpatch: allow space between colon and bracket

From: Heinrich Schuchardt
Date: Tue Apr 03 2018 - 15:17:27 EST


Allow a space between a colon and subsequent opening bracket.
This sequence may occur in inline assembler statements like

asm(
"ldr %[out], [%[in]]\n\t"
: [out] "=r" (ret)
: [in] "r" (addr)
);
