Type of 'probe_rsp->rawData[1]' is 'hcf_8' which is 'u8', it will compare with 'int', so use min_t() to cast to 'u8' to avoid related warning. If use min(), it has '(void) (&_min1 == &_min2);', so if no type cast, the compiler will report 'pointer types lacks a cast': drivers/staging/wlags49_h2/wl_main.c:3174:122: warning: comparison of distinct pointer types lacks a cast [enabled by default] Signed-off-by: Chen Gang <gang.chen@xxxxxxxxxxx> --- drivers/staging/wlags49_h2/wl_main.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers/staging/wlags49_h2/wl_main.c b/drivers/staging/wlags49_h2/wl_main.c index 35d617d..4d822e6 100644 --- a/drivers/staging/wlags49_h2/wl_main.c +++ b/drivers/staging/wlags49_h2/wl_main.c @@ -3171,7 +3171,8 @@ void wl_process_mailbox( struct wl_private *lp ) memset( ssid, 0, sizeof( ssid )); strncpy( ssid, &probe_rsp->rawData[2], - min(probe_rsp->rawData[1], + min_t(u8, + probe_rsp->rawData[1], HCF_MAX_NAME_LEN - 1)); DBG_TRACE( DbgInfo, "(%s) SSID : %s\n", -- 1.7.7.6 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
