Inconsistency in scripts/checkpatch.pl

[Larry Finger]

Andy and Joe,

In some new rtlwifi code, I get the following for one of the new macros:

CHECK: Macro argument '__h2c' may be better as '(__h2c)' to avoid precedence issues
#45005: FILE: 
drivers/net/wireless/realtek/rtlwifi/halmac/halmac_original_h2c_nic.h:1163:
+#define AOAC_RSVD_PAGE3_GET_LOC_AOAC_REPORT(__h2c)                     \
+       LE_BITS_TO_4BYTE(__h2c + 0X00, 16, 8)

When I make that change, I get

CHECK: No space is necessary after a cast
#45004: FILE: 
drivers/net/wireless/realtek/rtlwifi/halmac/halmac_original_h2c_nic.h:1162:
+       LE_BITS_TO_4BYTE((__h2c) + 0X00, 16, 8)

Which CHECK should I fix? To my eye, the second form is the false positive.
