From f261172d39f358dcecce13c310690d3937e0cca6 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 17 May 2024 22:40:20 +0300 Subject: spi: bitbang: Use typedef for txrx_*() callbacks With a typedef for the txrx_*() callbacks the code looks neater. Note that typedef for a function is okay to have.
