Subject: [PATCH] 2.5.62: /proc/ide/cs5520 returns incomplete data [5/17]
Date: Sun, 23 Feb 2003 00:56:20 +0200 [thread overview]
Message-ID: <20030222225620.GD2996@ttnet.net.tr> (raw)
This patch fixes the incomplete data return problem of /proc/ide/cs5520.
When the number of consecutive read bytes are smaller than the total
data in cs5520_get_info(), the second read() returns 0.
