Subject: command, log: print with "log show" a full logbuffer
X-Git-Tag: v2012.04-rc1~14
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c16a123fd34256859efc789b0bcde3e029b0d12a;p=oweals%2Fu-boot.git

command, log: print with "log show" a full logbuffer

If the logbuffer contains LOGBUFF_LEN chars, they never got
printed with the "log show" command, because chars get
printed with the following for loop:

for (i = 0; i < (size & LOGBUFF_MASK); i++) {

with size = LOGBUFF_LEN and LOGBUFF_MASK = (LOGBUFF_LEN-1)
for loop never executed ...

Fix this.
