If anyone has any objections, please let me know. ------------------ From: Sergio Paracuellos [ Upstream commit 619102313466eaf8a6ac188e711f5df749dac6d4 ] When CONFIG_OF is disabled then the matching table is not referenced and the following warning appears: drivers/clk/ralink/clk-mtmips.c:821:34: warning: unused variable 'mtmips_of_match' [-Wunused-const-variable] 821 | static const struct of_device_id mtmips_of_match[] = { | ^ There are two match tables in the driver: one for the clock driver and the other for the reset driver. The only difference between them is that the clock driver uses 'data' and does not have 'ralink,rt2880-reset' compatible. Both just can be merged into a single one just by adding the compatible 'ralink,rt2880-reset' entry to 'mtmips_of_match[]', which will allow it to be used for 'mtmips_clk_driver' (which doesn't use the data) as well as for 'mtmips_clk_init()' (which doesn't need get called for 'ralink,rt2880-reset'). Doing in this way ensures that 'CONFIG_OF' is not disabled anymore so the above warning disapears.
