The scsi and cfg80211 plugins cast between unsigned long long and
pointers, which is problematic for architectures where unsigned long
long is wider than the native pointer size:
linux/tools/lib/traceevent/plugin_scsi.c: In function ‘process_scsi_trace_parse_cdb’:
linux/tools/lib/traceevent/plugin_scsi.c:408:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
scsi_trace_parse_cdb(s, (unsigned char *) args[1], args[2]);
linux/tools/lib/traceevent/plugin_cfg80211.c: In function ‘process___le16_to_cpup’:
linux/tools/lib/traceevent/plugin_cfg80211.c:11:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
uint16_t *val = (uint16_t *) args[0];
This patch adds an intermediate cast to unsigned long, silencing the
warning.
