From fc533e25623af76d0e6ff87681a7c3122df1607e Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Fri, 9 Sep 2022 23:10:24 +1000 Subject: spi: Make 'default_spi_send_command' the default unless defined A NULL func pointer is necessary and sufficient for the condition `NULL func pointer => default_spi_send_command' as to not need this explicit specification of 'default'. Therefore drop the explicit need to specify the 'default_spi_send_command' callback function pointer in the spi_master struct. This is a reasonable default for every other driver in the tree with only a few exceptions. This simplifies the code and driver development.
