[PATCH 2/2] remoteproc: qcom_sysmon: Solve function header bitrot issues

[Lee Jones]

Looks as though 'name' has now been moved into 'struct sysmod_event'
which is passed in instead.  However, the parameter descriptions were
not updated at the same time.  Let's do that now.

Fixes the following W=1 kernel build warning(s):

 drivers/remoteproc/qcom_sysmon.c:78: warning: Function parameter or member 'event' not described in 'sysmon_send_event'
 drivers/remoteproc/qcom_sysmon.c:78: warning: Excess function parameter 'name' description in 'sysmon_send_event'
 drivers/remoteproc/qcom_sysmon.c:350: warning: Function parameter or member 'event' not described in 'ssctl_send_event'
 drivers/remoteproc/qcom_sysmon.c:350: warning: Excess function parameter 'name' description in 'ssctl_send_event'
