From 81ea9a0710bcf74934446f63898f0186aeb2b5b8 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 28 May 2023 12:58:30 -0700 Subject: [PATCH] spi: spi-sn-f-ospi: Make read-only array `width_available` static const The `width_available` array is currently placed on the `f_ospi_supports_op_width()` function's stack. But the array is never modified. Make it `static const`. This makes the code slightly smaller and more efficient.
