Subject: fs: exfat: Inhibit "impossible" print on write to bogus file
X-Git-Tag: v2025.07-rc1~44^2~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=21b04b3d72cfea587a8b616410371a191768c5e7;p=pandora-u-boot.git

fs: exfat: Inhibit "impossible" print on write to bogus file

Write into a bogus file, like '/.', triggers an "impossible"
print from the exfat core code. That should not be printed
in U-Boot, because U-Boot prints its own error message sooner.
Inhibit this error message.

The following command triggers the bogus print:
"
=> save host 0:0 1000008 /. 0x10
"
