mac80211: Do not use sizeof() on pointer type
The rate_control_cap_mask() function takes a parameter mcs_mask, which GCC will take to be u8 * even though it was declared with a fixed size. This causes the following warning: net/mac80211/rate.c: In function 'rate_control_cap_mask': net/mac80211/rate.c:719:25: warning: 'sizeof' on array function parameter 'mcs_mask' will return size of 'u8 * {aka unsigned char *}' [-Wsizeof-array-argument] for (i = 0; i < sizeof(mcs_mask); i++) ^ net/mac80211/rate.c:684:10: note: declared here u8 mcs_mask[IEEE80211_HT_MCS_MASK_LEN], ^ This can be easily fixed by using the IEEE80211_HT_MCS_MASK_LEN directly within the loop condition.
