-Subject: [PATCH] MIPS: BCM63XX: drop unused and broken DSP platform device
-
-Trying to register the DSP platform device results in a null pointer
-access:
-
-[ 0.124184] CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 804e305c, ra == 804e6f20
-[ 0.135208] Oops[#1]:
-[ 0.137514] CPU: 0 PID: 1 Comm: swapper Not tainted 4.14.87
-...
-[ 0.197117] epc : 804e305c bcm63xx_dsp_register+0x80/0xa4
-[ 0.202838] ra : 804e6f20 board_register_devices+0x258/0x390
-...
-
-This happens because it tries to copy the passed platform data over the
-platform_device's unpopulated platform_data.
-
-Since this code has been broken since its submission, no driver was ever
-submitted for it, and apparently nobody was using it, just remove it
-instead of trying to fix it.
-
-Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs.")
