From 78cfd833bc04c0398ca4cfc64704350aebe4d4c2 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Thu, 20 Nov 2025 13:06:39 +0000 Subject: firmware: cs_dsp: Factor out common debugfs string read cs_dsp_debugfs_wmfw_read() and cs_dsp_debugfs_bin_read() were identical except for which struct member they printed. Move all this duplicated code into a common function cs_dsp_debugfs_string_read(). The check for dsp->booted has been removed because this is redundant. The two strings are set when the DSP is booted and cleared when the DSP is powered-down. Access to the string char * must be protected by the pwr_lock mutex. The string is passed into cs_dsp_debugfs_string_read() as a pointer to the char * so that the mutex lock can also be factored out into cs_dsp_debugfs_string_read(). wmfw_file_name and bin_file_name members of struct cs_dsp have been changed to const char *. It makes for a better API to pass a const pointer into cs_dsp_debugfs_string_read().
