Subject: Variable-length arrays considered bad
Date: Thu, 08 Mar 2018 10:40:44 +0200	[thread overview]
Message-ID: <87zi3j9cz7.fsf@codeaurora.org> (raw)

Hi,

in an lkml discussion[1] it was mentioned that variable-length arrays
should not be used. Few warnings were found[2] from wireless:

drivers/net/wireless/ath/ath9k/dfs.c:104:2: warning: ISO C90 forbids variable length array 'max_bin' [-Wvla]
drivers/net/wireless/rsi/rsi_91x_sdio.c:570:2: warning: ISO C90 forbids variable length array 'temp_buf' [-Wvla]

Patches welcome.
