Subject: [PATCH v7 1/6] PCI/sysfs: Use sysfs_emit() and sysfs_emit_at() in "show" functions
Date: Fri, 4 Jun 2021 13:32:25 +0000 [thread overview]
Message-ID: <20210604133230.983956-2-kw@linux.com> (raw)
In-Reply-To: <20210604133230.983956-1-kw@linux.com>
The sysfs_emit() and sysfs_emit_at() functions were introduced to make
it less ambiguous which function is preferred when writing to the output
buffer in a device attribute's "show" callback [1].
Convert the PCI sysfs object "show" functions from sprintf(), snprintf()
and scnprintf() to sysfs_emit() and sysfs_emit_at() accordingly, as the
latter is aware of the PAGE_SIZE buffer and correctly returns the number
of bytes written into the buffer.
No functional change intended.
