[PATCH 2/3] irqchip/renesas-rzv2h: Kill swint_names[]

From: Geert Uytterhoeven

Date: Fri Apr 03 2026 - 04:54:45 EST


The array swint_names[] just contains expansions of "int-ca55-%u".
Replace it by formatting the strings where needed, to improve
readability.

Despite the two error messages can no longer be shared with the ICU
error cases, this reduces generated code size by 56 bytes.
