Nathan Chancellor ebceef298c mISDN: Update parameter type of dsp_cmx_send() ... commit 1696ec8654 upstream. When booting a kernel with CONFIG_MISDN_DSP=y and CONFIG_CFI_CLANG=y, there is a failure when dsp_cmx_send() is called indirectly from call_timer_fn(): [ 0.371412] CFI failure at call_timer_fn+0x2f/0x150 (target: dsp_cmx_send+0x0/0x530; expected type: 0x92ada1e9) The function pointer prototype that call_timer_fn() expects is void (*fn)(struct timer_list *) whereas dsp_cmx_send() has a parameter type of 'void *', which causes the control flow integrity checks to fail because the parameter types do not match. Change dsp_cmx_send()'s parameter type to be 'struct timer_list' to match the expected prototype. The argument is unused anyways, so this has no functional change, aside from avoiding the CFI failure.
